RE: Dual tank fill-up to top
The fill necks are too low. The after market bed manufacture has them too low.
Assuming this is correct - what is the fix? Thanks!
Had a sort-of-kinda-like problem on my recently sold dump truck. First thing to look for is whether the fuel fill spot ("fuel cap") is higher than the tank(s). Second, if the "fuel cap" is indeed higher than the tank(s), does the fill pipe run between the cap and the tank in such a way as to allow fuel to gravity flow down or is there either an extended run of level fill pipe or does the fill pipe even run "uphill" from the fuel cap before dropping down into the tank.
On my truck, it was the latter situation: there was a slight, very slight, uphill run between the cap and the first bracket on the hose. For whatever reason, it would fill fine until the tank was 3/4 full, then I couldn't get any more fuel in the tank...it would just come back out. I lengthened the bracket, had a local shop shorten and straighten the fill pipe (so it ran entirely downhill between the cap and tank) and the problem was resolved.
Another option of course is to put the fuel cap at a higher location on the bed, but that's probably difficult with the aftermarket bed.
Interesting. Well, I took photos and I found two things. Only the back tank has a 3rd hose that is capped (is that the vent hose)? Otherwise, yeah, there seems to be a slight drop but I cannot tell if it is sufficient or not. I am posting links to the photos.

RE: Dual tank fill-up to top
Why would they put a fuel fill on the front tank if you weren't supposed to use it?
As others have said, sounds wrong.
I understand and I agree about the "why".

RE: Dual tank fill-up to top
Definitely doesn't sound right. Sounds like the tanks are not venting. Get it checked out.
Thank you!

RE: Dual tank fill-up to top
That sounds faulty to me. I would suggest taking it to the dealer to investigate. On the surface it sounds like the tanks area not venting properly during fill.
Thanks!

Dual tank fill-up to top
Hello all.
I am 7,000 miles into owning a brand new '21 Chevy crew cab, cab chassis 4x4 DRW gas truck that came with dual fuel tanks (40 + 23.5 gal).
In the whole ownership of the truck, I have successfully filled it up full maybe 1/3 of the time.
It is my understanding that you are not supposed to use the front tank for fill-ups, correct? I tried a few times and it spat fuel back immediately so I concluded that the back tank is to be used. The way I understand it is that fuel flows from back tank to front tank, yes?
When I use the back tank, I have to open the front tank first to "depressurize" (get air out of) the whole system - this I found out on my own - without that the back tank spits fuel out as well. Is this correct?
After I do this, I am able to fuel up but often I can only get to between 3/4 and full on the gauge. After that, it spits fuel back from the back tank as well.
What gives? Is my fuel system faulty or is this normal? Are they this finicky? Thanks!

RE: Chevrolet 6.6 burning oil
I’ve got a mint condition 2016 Silverado 2500 CC 4x4 and the 6.0 with 4:10’s that just turned 60k miles. I get asked often if I’d sell it. The answer is always no. Or at least no one has offered enough yet! Think I’ll hang on to her a while as posts like this are all to common on different forums.
As far as the 7.3 Ford gassers. We run a number of them in our ambulance fleet. 11 ambulances with a distributed call volume of 23,000 plus a year. Also have 4 F250 Battalion Chief trucks with them. One truck is at Ford now for engine replacement due to a lifter issue at 12k some odd miles, 2 ambulance have had engine replacements (one lifter, the other I believe valve issue going down into the engine) and numerous other issues like plug wires, coolant leaks, and oil consumption. Now admittedly, the ambulances get run hard. But all were low mileage issues, like well under 50k miles. I know the engine really hasn’t been out that long. But so far, they have been nothing like the pre 2020’s that had the 6.8. At least for us. Those engines took a beating and kept on rolling! YMMV.
Interesting to hear about your department's experience with the 7.3 gas. We don't have any yet, have 5 ambulances with the Ford V10. Just like your department, the guys beat them like rented mules and we have no problems that I've heard of. Most departments in our area are going with the diesel Ram 4500 for ambulance chassis, despite the extra length and cost.
Our logistics and acquisition folks have explored this option as well. However, our shop guys have basically wrote off diesel engines and fight them tooth and nail in our EMS units due to all the idling time and emissions issues. We have ordered solely gas since roughly 2016 in ALL Med units. And yes, the 6.8 was solid as a rock. I feel like the 7.3 may get there, it just isn’t there yet.
There is now a 6.8L gasser being offered in the XL trim on the HD trucks if I am not mistaken.

The 6.6s have been out since 2020 - there are plenty of trucks now that are higher mileage. The consensus is that there were issues with brakes (loud like trains) and a few electronics issues like dead radios etc. Oil consumption has been talked about in all the groups every now and then but the consensus is that the majority of the trucks do not consume oil and the ones that do - do it within the GM guidelines/expectations (there is a 2020 bulletin about it). I think GM did the right thing to pair the new engine with the tested 6-sp tranny and that way work out all the bugs / limit the variables that could go wrong. Now GM is going to the 10-sp tranny and some people are ecstatic, some are not. Overall, the 6.6s have shown to be good and strong engines and IMHO the most reliable/least problems from all the 3 HD gas engines. Not the most powerful but most reliable.
p.s. this is from the GM TSB:
"Oil consumption of 0.946L/379L of fuel (1 qt./100 gal.) or less is considered acceptable."

RE: Valve stem extenders for inner wheels (DRW)
This is what I use. Just aired up today for the trip North tomorrow. EEZ-PEE-ZEE.
Last pic, love the screw on caps with check valve.

RE: Valve stem extenders for inner wheels (DRW)
Carry your own air compressor with the ability to change chucks. Not that expensive and it keeps you from being at the mercy of whatever air compressors you can find. A hundred dollars or so for your own compressor is chump change considering what you have.
I do carry it but I don't think it will accept different chucks. I agree with you - will just buy a proper portable compressor that does. Thanks! :)You probably don't need to buy another compressor. The chuck most likely just screws on and you can buy an adapter from any decent hardware store that will allow you to change chucks easily for less than $20.
Thanks. I will try that first.

RE: Chevrolet 6.6 burning oil
Thanks guys for all the input! I am just extremely particular about my vehicles, and hate the thought of needing to carry extra oil at all times!!
Tough decisions on if I trade in, (and fortunately will get every dollar back that I got in it) and get another GM hoping this one was out of the ordinary, or try out a Ford...
People who own the Godzillas seem to be happy with them. It is a nice engine, top of the offering in the gas world right now. Ford even introduced a 6.8L gas engine in the XL trims - so you might want to check that out. I am happy with the 6.6L GM/Chevy gasser, does what I want and does it without a fuss. I am not brand loyal, test drove all three for months and joined all the Facebook groups, followed them to find out all the issues the engines/trannies were having etc. I came from the diesel world (never going back)- the new gassers are potent and do their jobs well. If you think about it - people rave about the 7.3L powerstroke from 20 years ago - well the gassers have double the HP and the same torque but with computer controlled transmissions and very smooth power delivery curves, same level of simplicity (comparably) and cheapness of maintenance. Win-win.

RE: Chevrolet 6.6 burning oil
Whoa, sorry for being a month behind on GMs next years models….lol.
Well good, GM finally pulled their heads out of their posteriors.
Now Ram is the only one left running 100% outdated transmissions in some of their HD models (aka all the diesels).
A lot of people like the 6-sp. It is a known entity, it is paired well with the 6.6L gasser and it is dialed in very well as to where it delivers a smooth power curve and it does it effortlessly. I test drove 10-speeds multiple times (Ford 7.3L gasser) and I went and I test drove the new 10-sp with the 6.6L Chevy. The trannies were constantly shifting and it annoyed the **** out of me. The 6-speed GM trannies are known entities, have been around for years, they are super cheap to replace when they go out. 'Nuff for me. Not every new thing is a good thing for everyone ;) (how many people have left the diesel world because of CP4 pumps?).
I can even see the point of the 10-sp if you offer different gear ratios but GM is stuck on the 3.73 only whereas Ford offers everything from 3.55 up to 4.30. So what exactly to you get with a 10-sp on the GM gassers? Maybe slightly better gas mileage (although people are reporting pretty similar numbers with the 6-sp) and maybe better towing up the steepest grades. But then I always think to myself - people have been towing up steep grades since 50+ years ago with much less powerful trucks and did it just fine - whether I get to the top of the hill in 15 minutes or 18 minutes - who cares? ;) Me personally, I am after simplicity and longevity, not the shiny new thing...

RE: Valve stem extenders for inner wheels (DRW)
The problem is - I have a portable compressor (the kind that connects to tow vehicle battery) - and that one does not really accept different chucks etc. Also, how is a long chuck going to help me if I have to air my tires at a gas station while traveling? Unless I am not understanding something here...(there might be a language barrier, I live in the States but am not American by birth so not sure if I understand what a "chuck" is). Thanks.
I call the piece that attaches to end of hose, locks on valve stem the "Chuck"
Now as for the "not really accept". I have that kind of compressor in pickup and DW's car. But mine where made by man, not created by a god. When I tested both would pop off as soon as I let go of it. Man made it, I paid for it, so I have no issues changing it. (I don't use a quick-couple, only because I only use for tires. I want the chuck to be on hose so don't want to look for it.
As for air at gas stations; In the area you travel will the station compressor work when you need it? And if it works, will it put out enough pressure to air your tires? And do it without overheating/shutting down? (I have tried to use them on bicycle tires. Success was limited to the point I carry a hand pump now). If your tire takes 50PSI and pump maxis out at 60, it will take a long time to inflate tire. Plus the issue, you drove to station on under-inflated tire, so no longer cold. What pressure you set it to?
Thank you for taking the time to explain. I am a fluent English speaker but sometimes uncertain of "technical" terms :)
When hauling my truck camper on the flatbed (and I always have the horse trailer in tow with the camper since we camp with our horses only) - my rears are at max pressure - 80psi - I am almost at GVWR for my vehicle fully loaded/hooked up. As you suggest - I think what I am going to do is get a proper portable compressor to take with us - one that accepts different chucks :).
Thank you!

RE: Valve stem extenders for inner wheels (DRW)
Longer valve stems only help if you only put them on the inner dual AND if you never rotate tires.
If you put longer valve stems on the outers, all that will do is extend them further inward, making them more difficult to reach.
I have two different types of dually air chucks, though, and NEITHER are the right angle to get on my factory valve stems on the stock steel wheels of my 2002 Chevy 3500 DRW. I have the angled one, and the straight-on one with the angle. Can't get straight on any of the stems.
Yeah, none of this stuff I heard so far sounds like a perfect solution...

RE: Valve stem extenders for inner wheels (DRW)
Thank you all - I see most experiences are negative with the extenders. I did get a pair from Amazon and they did not fit well. One of them got ruined by the local Chevy dealer so they tried to make good on it by buying me a replacement (steel mesh flexible ones) but they could not even install those - leaked before even leaving the shop. I guess I am going to talk to the local tire shop about longer valve stems, as someone mentioned. The problem is - I live in a rural area and there are not that many tire shops - the ones that there are - I don't trust them much.
Sounds to me like you have missed the main point of most replies. Get the right chuck and gauge. Then the factory valve stems work as designed.

RE: Chevrolet 6.6 burning oil
Grit: 2024 has the 10-sp. Personally, I am keeping my '21 6.6L with the 6-sp. Unless you have driven this truck with this engine - the tranny is dialed in perfectly on the 6-sp.
As for oil burning - I think about 10% of the users on the Facebook 6.6L gasser group complain about it. There was a TSB issued by GM in 2020 about it but it only mentioned the 2020 models and was never extended to 2021 etc. I am not sure that this detail matters, given that it is the same engine. My '21 is not consuming oil, for example, however, I have been told by a dealer that some oil consumption is normal. Check your oil regularly like with any other vehicle you have ever owned?
Other than that - I think everyone who has towed/hauled with one of these trucks has been pleasantly surprised, myself included - and I came from an '06 Duramax/Allison and a '16 6.7L Powerstroke. Like some people here seem to have a visceral hate of GM - after owning the Powerstroke - I now have a deep disdain for Ford's quality control. If you are looking into gassers, Ford's 7.3L Godzilla sounds like a better/bigger/stronger engine but if you have ever been burned by owning a Ford that had all sorts of problems, well, the GM is the ticket. BTW, if you are worried about oil consumption - this is the only "problem" with these engines. Spend some time on Facebook on the 7.3L Godzilla groups to see the litany of issues they have been having with everything from spark plugs to transmissions to.... Same with the 6.4L HEMIs - the 8-sp ZF tranny may sound great but then ask about the lifter issues. I conducted a survey on the 6.4L HEMI FB group when I was doing research on the gassers and 11% of the owners on the group reported a lifter problem early into the truck's ownership.

RE: $100,000 Host Campers
What I would like to know is where are people finding the money to buy these things? They are "flying off the shelves" and even a what used to be a measly $25K Palomino 2902 or 2910 is now $39K in my neck of the woods. Inflation is a part of it - is the other part supply chain stuff? Still, who is buying all of this new at these prices? If you are going to buy a $100k camper - you probably have at least a $80K truck, if not more. I am on a couple of Facebook groups that deal with flatbed truck campers and people are spending $70 or $80K on an F-550 just to throw away the DRW back end and sub it with a "super single" - something that probably costs $20-$30k. To me this sounds incredibly stupid (but hey it is Amurica so free to burn your money any way you want). We keep hearing how nobody wants to work, it is the "gig economy", blah blah yet these things sell like hotcakes....I am puzzled.
