RE: GM 6.6 & 3:73

OP, you might want to add some info on what you plan to tow. I towed an 8-9000lb TT with a GM 8.1 gasser back ~15yrs ago. It pulled well (except up steep grades in Rockies) and never passed a gas station without stopping. Pulled 14-17k 5ers the last 10yrs with diesels…no comparison.

RE: battery to inverter wiring

Drawing large loads like 150A will have IR drop in the cabling as you’re aware, but internal resistance in the batteries will also come in to play at high loads like that. If you switch to Li you’ll not only gain an advantage of lower internal resistance, but also higher starting voltage (at an obvious cost $$)

RE: Will a 3/4 ton do

You’ll run out of rear wheel capacity to carry the pin weight. 1Ts don’t cost much more and add additional rear suspension, I’d recommend giving them a serious look. Even with a 1T you won’t have a lot of excess RAWR.

RE: Tonneau Covers

I used a TonnoPro for 9yrs on my Chevy 3500 SRW with a Superglide hitch. Soft, not hard, but held up well to feet of snow in MN. Just replaced my TV with a 2022 F350 SB (again using a Superglide hitch), and the first accessory I ordered was another TonnoPro. Easily folds over bed when not towing, fold to front third when under tow, and detaches completely in a minute to place things in front or to access what it’s covering. It’s inexpensive as tonno’s go, I definely recommend it.

RE: Sumo Springs on 2022 F350 SRW

Interim Update Spent a while on the phone with Sumo Tech Services Mgr - great guy, and fabulous support! He commented that the Sumo (or bump stop etc) does not travel in a straight line relative to the lower perch stop, which is rounded and angled to intersect accounting for this. He took my installation specifics, weights, etc and believes that all is correct but that potentially a bump or something temporary ‘overloaded’ the Sumo causing it to swish sideways in attempt to relieve this and sliding off of the perch; once off it no longer functions properly and was tore apart with further bumps. He wanted further specifics (which I sent tonight), but called me back to say that he’d already set replacement parts aside (including platforms to prevent a similar problem in the future) awaiting an address to intersect my travel. He also commented that leaving a little bit larger initial unloaded gap could also minimize this issue. Can’t say enough good about Sumospring responsiveness so far!! Hope to get this resolved within the next few days and then a couple thousand miles traveling the Rockies over the next 4-5 weeks should give the resolution a good test. Thanks for all the replies and information. Hope to report back good news in a month :)

RE: Sumo Springs on 2022 F350 SRW

Fj12ryder - yes. Bigger and spongeeer bump stops that eliminate a couple inches of squat…unless they tear off like mine did…

Sumo Springs on 2022 F350 SRW

I installed 2800lb Sumo Springs (yellow) on my F350 a week or so ago. Have pulled our 5er ~1k miles with them and found one of them torn nearly in two, and the other one starting to have a banana bend. I noticed that they didn’t contact the bump stop directly in the middle when installing and suspect that’s the cause. I have an emai in to sumosprings but don’t expect an answer for a couple days given it’s the weekend. Has anyone had this issue? TIA

RE: Superglide Clean bed rails

1-1.5" sounds high, but a gap is normal; I think mine had about 1/2" gap between the bottom of the rails (resting on the flange in the pin) and the truck bed.

RE: Not one but two blowouts

Lots of heavy 5er's come with inadequate low quality E rated tires. Many don't have problems; but some tire scrubbing, overloading, running fast, road hazards, sun, or just every day bumps can make them very dangerous. Some replace with LT's, many just replace with good G rated ST tires. They don't have to be expensive, Sailun makes a good G rated ST tire that I've run on two heavy 5ers very happily for tens of thousands of miles. If you have a heavy 5er with E rated tires I'd recommend replacing them soon with G's.

RE: Trailer Brakes Disconnected message

What agesilaus said. Plus you might try using a screwdriver and bending the prongs a little tighter.

RE: Explain how emergency trailer brake gets power?

Pretty sure that emergency trailer brakes are direct connected to the battery through the break-away switch; no fuses, no breakers, no other switches etc. If you pull the break-away pin they should supply full battery power to the brakes.

RE: Theoretical heights.

There's usually an AC on top of that roof that you haven't accounted for

RE: Removing Shower Doors

We removed the glass shower doors in our 2019 Vilano 320 and put an articulating rod and curtain in it's place; best mod (of many) we've made. More room when you're in the shower, more room in bathroom when you're not, no cleaning glass doors, and no *trying* to clean the track. Not sure how it would work with a corner shower though. Recommend you search out a manufacturer specific forum and see if others have done this.

RE: New Ranger for towing

Not many 5ers can realistically be pulled with an F150-class, can't imagine any that a Ranger-class TV would work with...

RE: Residential Fridge battery run time

willald - I have a similar set-up (or had until switching to Lithiums a month ago). 630AHr AGMs, Magnum 1k inverter on Samsung residential fridge, also a Magnum 3k inverter with 125A charger for whole-house. We found that our fridge alone would average 160AHr/24hr period. So if *nothing* else ran we could power the fridge for ~48 hours. I also am not adverse to running down to ~40% SOC once in a while. Practical experience with boondocking over a few years was that I didn't even think about battery capacity concerns if we plugged in every other night. When boondocking for a week or so I needed to average running the generator about 3hr/day, but didn't have to run it every day (but couldn't skip more than a day, and then needed to make up for the 3hr/day average).

RE: Residential Fridge battery run time

Our 2019 VanLeigh Vilano 320 has a Samsung residential fridge and Magnum 1k inverter. They draw approximately 160AHr per 24hr period. If you just have one standard lead-acid battery (85AHr) and only run it down to 50% before recharging (~12.0v, recommended if you want the battery to last very long), you will only get ~40AHr or 6hrs of running the refridgerator. Of course there are several variables, while driving your truck will supply a few AHr (mine does ~3A) which will add to your time, if you run lights, furnace, etc you will eat up some of that capacity, if your battery is not new or in good condition it won't provide the full charge, etc. Bottom line, you really should have at least 2 standard batteries just for campground to campground with a residential fridge in my opinion, the equivalent of 4 FLAs for overnighting, and at least 6 for much boondocking. I've added much larger batteries, and a whole-house inverter, to our 5er so that I can run everything and boondock for longer periods of time.

LT Tires

When I started driving in the '70's flat tires and blow-outs weren't uncommon. I can't remember how many tires I changed in parking lots or by the side of the road, but it was more than a couple. In particular I recall a blow-out in some miserable weather in MN, fortunately it was a rear tire. Since radials took over in the 1990's I haven't had any blow-outs and now my tires just fail when I pick up a nail or screw it seems. This thread is NOT intended to discuss trailer tires, nor the ST vs LT debate on them, but I'm curious of forum members experience on tow vehicle LT tires. Has anyone had a blow-out on LT tires in the last 10-20yrs? Even if overloaded? Thanks

RE: Not the cells that fail it is the battery Management System!

Gdetrailer - to TechWriter's point, I'm having a hard time following the statistics from your experience. Can you shed further light? I did read the attached link from the OP, good background info on LFPs. But I agree that the 99% claim sounds like it's not backed up by real data. Regardless, if the LFP failure rate is small (1%??) it may not matter to the real world user if the root cause of the failure was the BMS or cells. Would be nice to see some real failure rate data on LARGE sample sizes but I suspect manufacturers guard that pretty closely. It sounds like this thread has scared at least one away from a turnkey solution, that's up to every individual's personal critical thinking, but with BB 10yr warranty I think there are more concerns and potential issues going with build-your-own and wouldn't recommend that without some real understanding on the users part above and beyond forum gossip.

RE: Walmart 27DC….80 or 109AH?

If the sticker says 80AHr, that's probably what you got. 20hr run down rate is typically how batteries are classified for capacity, things like 'cranking amps' don't apply for camping use. If you're installing two, you'll probably get more capacity (as well as battery design robustness) by installing two 6v golf cart batteries in series. Sams and Costco seem to have the best deals on these typically.

RE: Break-even point between cable length and voltage drop?

Gdetrailer et al - check my math here, good catch on return path: Simple answer, solar panel placement affects charging more than the difference between 40ft and 70ft of 10ga. More complex answer: Based on OP's first post the controller puts out 14v and he measured 13.8v at battery and 13.5v at battery on 40/70ft runs. This would imply with 40f he is getting 2.5A charging current (200mV drop across 80ft (round trip) at 1mOhm/ft); and at 70ft he's getting 3.6A charging (500mV across 140ft...). The reality is that his measurements etc aren't that accurate and I'm sure that he's getting roughly the same current charging with either run, the limiting factor in his charging is *not* the IR drop in the wire, but the internal IR drop inside the battery (if you will, actually more complicated). The truth is that with ~13.5v across the terminals the battery when nearly fully charged is the current limiter and isn't accepting much current. If he did the same experiment with 50% discharged batteries (12.1v) he will be putting a larger voltage differential onto the batteries and will drive more current. In this case the wire IR resistance might come in to play but I'm guessing second order compared with sun exposure on solar panels. Assuming full 7A charging from his panels he'd be putting ~13v across the battery with 70ft (including round trip) and 13.4v with 40ft; I suspect a 50% depleted battery will draw 7A regardless of 13v or 13.4v across it, and as it charges up the battery internal resistance will be a larger current limiter than the IR drop (as evidenced by his measurements in the first place). Thoughts?
