RE: Will a 3/4 ton do

Thought the point if these rv.net forums was to advise those asking for help...not going into the weeds on HOW2 circumvent the OEM ratings... Of which am likewise guilty... Came over here while still owning a Suburban forum and many asked about XYZ & ABC, which felt was not applicable to forum members situation Forum was taken over by spammers and not enough offered to contribute for better software, so shut it down

RE: Will a 3/4 ton do

And why have been saying that anyone who asks does NOT understand and best to advise them to go by the OEM's specifications/ratings. Go out and weigh it all, axle by axle and then do the simple math Shiner...thanks for the details. Knew most of that from a broader point and your details are very good. Made a copy for my reference Also have been saying for years and years to use the OEM's ratings instead of the marketing nomenclature...but that again is too confusing to those who have to ask... OEMs sell many more vehicles to those who bought the wrong one... Grit...that boss is a pure bean counter manager and the legislators who writeup the laws governing this stuff usually are clueless. They should stick to counting beans and stay away from science & technology based topics PA12DRVR...your story reminds of a buddy who was in the Navy during the 60's-70's and told of what they told him if they ever 'heard' steam escaping. Invisible and that stream was hot enough & escaping fast enough to cut a body in half...told to take a broom and wave it slooowly around and found when the broom was cut in half...don't know how true that one was All things engineered/designed/etc are not for the good days, but for the Mr Murphy moment and for the Idiot Gorilla who will misuse whatever they have...taught to me early in my designing career. Seems today's designers are never taught that

RE: Will a 3/4 ton do

Wish there was a like button... What would happen to the operators of that crane if they went over rated load ? Even though they knew the posted load rating...know the answer and rhetorically asking for the group First career was in industrial motor controls and one market sector was cranes (material handling). Circa late 60's to mid 80's Know they had engraved metal ratings labels riveted to the crane, operators cab and on the pendent controller Our computers would have recorded, sounded an alarm at each overload attempt and refused to move after a preset number of trys. Some required a keyed reset after reaching those numbers of trys...this is why said pretty soon, OEMs will control more to all ratings like they now do with ICE rev limiters Nuclear and military had more onerous notifications and margins vs civilian of the exact same mechanicals...though they often had locational requirement in the +/- 0.03 inch at some tonnage, which had additional mechanicals, etc Prefer stout's or porter's Tire ratings / axle ratings are just like Over Head Crane ratings.. They are rated to a certain rating with a safety factor on top of that.. They POST the rate based on every day usage.. Most people will see that they can carry XXX amount of weight and go full Hog till they cant.. I can assure you, If they rated our overhead cranes to 15 ton instead of 10 ton, we would be lifting 15T every day, all day... in a nut shell - There is a safety factor built into EVERYTHING with a MAX capacity.. just how much = ??

RE: Will a 3/4 ton do

Exactly and is more of OPs waiting for what they want to hear... Selective adherence to ratings...even the most anti-rating advisors revere some ratings But if the numbers don't matter, then why do the numbers on the tires matter? Asking for a friend.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Tusk is off chasing other bright, shining situations to continue micro managing the Cyber-copy...nor the semi Turtle...all of my guys said most are fearful of being fired on the spot, so everyone ducked and never told him the truth...except my guys...who all quit in time 10 gauge is on the line between sheetmetal and plate...wonder how big those brakes are to stop within NHTSA braking minimums... Did notice the reduction of the Cyber-copy wiper arm...but, now looking like the swept area might not clear vision for a tall driver...

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Am assuming Tusk also learned from that same Model 3 fiasco that True Dimensional Tolerancing played huge in that robot not being able to bolt the body to the skateboard pan One part from a 'well maintained' stamping vs crafted & assembled from many parts has tighter tolerances My guys quit during that fiasco (couldn't take Tusk's micromanagement and always claiming he was right and my guys wrong) and are now working down the road in Newark...my previous company's automated factory and is now Lucid's HQ snip... How ironic. Not that this is not new technology....most all vehicle panels and uni bodies are stamped. Along with 100s of other parts in ANY vehicle. But moreso, just hilarious that a vehicle that looks like the product of a high school sheet metal class or a very nice rendering of a Pinewood Derby Car, that the body panels could literally be made with a brake and a shear, is garnering the fascination of ole Elon8.1!

RE: Will a 3/4 ton do

If TV's fell out of the sky from going over ratings like airplanes would, then both the regulatory folks and owner/drivers would think differently...because when a TV is over and breaks or some such...they just roll to a stop on the side of the road Ditto other types of people movers. We were in the ski lift business for years (late 60's to early 70's), until lawsuits became outrageous & jury's applied 'current' safety standards to systems built, installed & approved/certified years to decades ago. Resort owners cutting budget & went over the ratings to have components run too hot, towers getting bent (they bypassed the cable derail sensors) and more You obviously know more about trucks than I do...I do not know for a fact that the axles on a 2500 and 3500 are the same. I only posted the results from my trip to the scale and compared them to the ratings on my truck and the ratings published for a 2500. I've been contributing to this forum since 2001, 11+ years before you joined, so if anybody is trolling it's you. The OP asked a question about weights and you're trying your best to turn this into an argument. I believe that ratings are there for a reason, you obviously think they are concocted for political reasons have have no basis in fact. As my Dad used to say, "You're entitled to your opinion, no matter how wrong it may be." The ratings are for warranty and registration purposes only. You can register a Tacoma to 14,000 lbs and load it up and be perfectly LEGAL, though I doubt it would move very far. There used to be a larger mechanical difference between 3/4 and 1 ton trucks, but the manufacturers long ago realized that it is much cheaper and easier to put essenentially the same rolling chassis under either truck and change the spring pack and the sticker on the door to meet the DOT requirements for a class 2B truck. The spring pack is easy to overcome, with helper springs, Timbrens or air bags. The sticker can simply be ignored and your truck registered for whatever weights you are willing to pay. My Ram has AAM 11.5" axles in the rear. They are rated to 12,000 lbs by AAM, derated to 7,000 lbs for the 3500 and 6,500 lbs for the 2500 with 18" rims, and 6,000 for the 2500 with 17" rims. Same axle. The brakes, wheel studs, engine, transmission, rear differential, bumpers, bed, body, tires, radiator, etc are exactly the same. The frame is slightly different, just due to the shock mounts from the 2500 coil to the 3500 leaf. Ram rates the coils at 500 lbs lower than the leaf springs. If that 500 lbs worries someone, they can put bags or Timbrens to make up the difference. The only reason that truck manufacturers make a 3/4 ton these days is to get into the class 2B market, which only allows a vehicle a max GVWR of 10,000 lbs. You can by a Ford F350 with a 10,000 lbs sticker, does that make it any less capable than an identical F350 with an 11,500 sticker?

RE: Will a 3/4 ton do

Yup, expected it going this way and ask "why did the OEM's install computer control to limit over rev'ing" Then...would the OEM's now manage other ratings ? They have most of the "stuff" NOW in current vehicles Like the several threads here both asking and showing off an aftermarket gizmo that can measure & display how much is being towed just by plugging into the computer port with nothing else to be added or changed...though that vehicle has to be an automatic, not manual Ditto payload, but there needs to be an addition of strain gauges to both axles Then just software like the current...modern...Redline limiter so that there isn't a redline on tachometers anymore Another are speed limiters, torque limiters, etc If enough folks ignore OEM ratings that then drive up warranty & service costs...yup, the OEM's will do something Finally, tuners and their ability to circumvent OEM ratings...but the OEM's have the fed's there to police tuner firms Edit..yup, am an old guy at 74 this year Been retired over 20 years from careers in automation, robotics, process controls, computers, etc and all associated with military applications Funny to continue to find that the basic algorithms are still recognizable to me. Their logic, flow, bubble, truth tables, etc all look similar to those of my day Difference is that the stuff has gotten ever smaller and integrated

RE: Will a 3/4 ton do

There is one OEM rating that all of the anti-ratings advisors do believe in and that is the ICE "red line" Haven't read anyone here recommend going over it...nor "I've been doing it for years with no problems"...or..."go for it"...

RE: Will a 3/4 ton do

Agree ! When it comes to science & technology discussions on these freebie forums...heck even my paid forums...too many advisors have no skin in the game in the OP's questions & situation Then the ratings misconceptions and even some who dismiss ratings will then reference another 'ratings' that they do follow On top of all that...they do know that all designs have some level of dialed in margin and is 'good for it'...of course yes...but for how long and how safely during that Mr Murphy moment. "Design margin" is a closely held secret and it would take a court order to disclose and then under strict NDA with large fines if they break the NDA Bottom line for me...if someone asks for this kind of advice...they don't know enough about that situation to make up their own risk management decision(s) and will reference them to their OEM's specifications & manuals for THEIR vehicle & setup To the many PMs asking, tell them to also look at the history of posts of the party they are asking me to either debunk or verify and make up their own minds if that advisor matches their own values Also agree with what Shiner said on another thread and is that am not coming over here as often as before Only in the RVnet forum would we boast about our favorite brand’s 3500 DRW being rated to tow more than 4 times its weight yet freak out when someone asks about an 8k lb HD 2500 truck towing 1.75 times its weight. Well, technically, that's accurate, but the paradigm is duplicated on other forums that I visit: - On a hunting forum, apparently Dall Sheep will instantly die and be magically transported to a landing strip if Experienced Hunter X even mentions going hunting, but when Hunter X responds to Newbie Hunter's question of the best method to stalk Dall Sheep, Experienced Hunter X simply states: "You'll never be able to sheep hunt unless you have 20 years experience"....and how pray tell does one get that experience? - Or on the airplane forum: Some PA-12 driver states: "I've landed on XYZ River Bar a few times, always a bit dicey to touch down soon enough if it's windy." (allegedly) Experienced Pilot X then asserts: "XYZ River Bar looks like it's at least 300' long, any Piper pilot worthy of the name can land there without a problem." PA-12 driver: "Have you ever landed there, particularly when the wind is from the East?" Pilot X: "Well, no, but I've flown over it once." :R

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

That guesstimate was based on current batteries Tusk uses...even his new 4680's Solid state, saline, diamond nuclear, etc will change all that. Some more than others Diamond nuclear batteries lasts forever and doesn't require charging...but it would take tens to hundreds of thousands or millions per vehicle. Still embryonic at this time Over 50 years ago, while in college working part time we designed MG-sets for Gyeserville. Early generators from steam But everything dessolved from hydrochloric acid mixed in with the steam. Tough environment that the epoxy paint on everything couldn't handle

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Have designed up to 2MW (also good to 10,000HP electric motor) and confirm his calculation range Even if any one charge station could muster that kind of power (the cables would be in the +500MCM gauge range or several +500MCM cables per phase) or buss bar but would still require some sort of flexible last few feet. Best would be a battery change out as the refueling method and a solar farm of several acres dedicated to that refueling station..and/or...supplemented with windgenerators The amount of energy needed to fast charge just one semi(let a lone a whole fleet) in the 30 minutes that Tesla states is huge or even over night is a lot more than places a long these major routes can handle. EE friend of mine did the calculation, I accept his calculation. To charge a semi given Musk's data of charging to 80% in 30 minutes on just one truck, would require 1.2 MW. Just ONE charging station. . When towing my 5er, I find many truck stops will have a dozen fueling stations, and most if not all are occupied or there are trucks waiting.

RE: thoughts on Ecoboost

Thanks Turtle...GREAT video ! Only have one issue and is with his mix up of gas vs diesel describing the fuel PSI. IMHO, most won't pick that one up, but that is the way of it Folks who argue dino vs synthetic engine oil won't get this one either. Yup, dino has come a long ways closing the gap with synthetic, but so has synthetic been improving at the same time. That additional headroom on specifications might make the difference down the road. Especially when it gets driven hard using that big block volumes of air/fuel in a tiny combustion chamber. That then gets into rejection thermal management of all of those BTU's and is with surface area between a small displacement vs larger displacement. That can be managed with higher flow rates of coolant, which up to a point tops out, and then the efficiency of each square inch matters. Play with temp differential to have higher transfer rates, to swirl, to better plenums both in & out (multi in & out paths of virgin coolant helps and is the why they had reverse coolant flow to the heads a few years) Lubrication, and why most of the higher priced oils now claim some sort of molybdenum sulfide these days. Am still adding my own last quart, which has been mixed in a blender with MolyB powder. Have some Tungsten disulfide powder, but limited 'cuz the buddy's firm bellied up and he dropped off the face of the Internet That added margin of better lube (the lowest coefficient of friction for additives...both MolyB and Tungsten) makes a huge difference in anything metal to metal. Like the chain-stretch wear from extreme pressure when the turbo's kick in. Cool video and like Dustin Golley. Smart guy showing his knowledge of the engineering & technology involved Here is a great video on the EcoBoost. The guy does a great job of talking about the good and the problems with this engine. When this guy talks about this being a high performance engine he is a 100% correct. This engine needs to be thought of as pretty much a race engine. As mentioned, race engines need impeccable maintenance. Another thing about this engine and engines like this. They don't have much duty cycle. That's why class 8 diesels have a big CID displacement in them. We can make big power with a little engine but when the weather turns hot and the mountains get steep you need that big mass to displace the heat the engine produces. In short, if you are going to pound on this engine day in and day out up steep mountains in hot weather this engine is not for you IMHO. If you are a weekend warrior and pull a trailer now and then in easy or moderate conditions this might be a great engine for you.

Need vs want...but IMHO there is another way to view that...

RE: Travel Trailer Towing Recommendations

Even more of an odd ball if it has the F60 snowplow option That begets a 1 ton front torsion bar setup and the rear is the same as the 1 ton dually of that year...why tongue'n cheek refer to my Suburban as a K3500 Exactly. For that reason and stricter federal fuel efficiency requirements, is why you don't see 3/4 ton SUVs. Actually, 3/4 and heavier trucks are under different efficiency rules. That's why you won't see an MPG number on the window sticker. But 3/4 ton SUVs were always an oddball item. Back in the day, if you had 6 or more passengers, the choice was a van or people would load them in the back of the pickup with a cap on it (yeah, it was a different time). Back in the day, it wasn't unusual to see 60% of the trailers in a campground being pulled by a van. Fast forward 30-50yrs and families have fewer members and a legitimate 6 passenger pickup is commonplace. The result is probably 75-90% of trailers are pulled by pickups. It's also changed 5th wheels from being focused on older retired couples to a family RV option.

RE: Travel Trailer Towing Recommendations

The OP already has the trailer : We just purchased our first travel trailer. We are looking at purchasing a new tow vehicle. Would like recommendations on what tow vehicle is best what to avoid. We will be towing a bunkhouse GVWR is 7,500 lbs. TIA for your recommendations. Repeat recommendation of a full sized van : Have a 1996 8.6K GVWR, K3500, 7.4L Suburban, but wanted a full sized 4x4 van, which wasn’t available back then…so settled for the 8 seat Suburban. Only half ton Suburbans are available to day, except for the armored 1 ton version, but only for VIP’s and the President and it’s tow rating is something like 3K Today, if I was you, I’d get a 2022 GM/GMC full sized van, with 12 seating, 2.8L/4 cylinder Turbo Duramax, 8 speed, 31 gallon fuel tank, 9.9K GVWR & 15K GCWR.
