Our 2020 Fuel F-287 came with some Trailer King RST tires and we've put about 700 miles on them so far. We are planning a summer trip to Colorado (about 1800 miles round trip) and I'm wary about going that far with them. So I'm planning to replace with some Goodyear Endurance ST's. First question: Trailer axles are rated at 6k each and GVWR of the trailer is 12,800. Fully loaded without a full tank of water and we are around 10,100 lbs on the axles. Guessing around 10,900 with a full tank of water, maybe a tad less. I'm considering 123N, which are rated for 3420lbs max load up to 87mph. Is this enough buffer? I would think so, but I'm no expert. Second question: I'm still not quite clear on tire inflation table figures. Obviously it's bad if you are under inflated, but is there any concern with running at 80psi all the time, regardless of load (so long as it's not over), or is it important to try and match PSI to load? My load will vary depending on toys we're bringing. Third question: Is there a standard PSI rating for a 6J wheel? Is it safe to assume the rims will handle the new tires since the current tires are also rated up to 80psi? Last question: Am I being too paranoid by replacing these tires so early? I'd hate to have them explode on our vacation. Are the Trailer King's good enough to get us through our trip before replacing, or am I right to think I should just ditch them now? Thanks all!Re: ProPride and lifted 3500Picture of truck with trailer: Re: ProPride and lifted 3500Thanks! This is exactly what I was looking for. It is less than 3 lbs and seems to be fairly compact. Is this the same model? https://www.dewalt.com/products/storage-and-gear/air-compressors/20v-max-cordedcordless-air-inflator/dcc020ib The Viair seems to be popular too, but 300 bucks seems like a lot for topping off tires. Although once you add the battery the dewalt isn't that much farther off, except that it can be used with other tools at least. EDIT: I must have posted before your link popped up. I'll pick one of these up. Thanks again!Re: ProPride and lifted 3500Dang, I'm not much of a RAM guy (mainly because it feels like less headroom), but that is a nice truck. I like the vintage chevy too. Grit dog wrote: On this scale, what would 40" Swampers be? "Pre-natal" tires? lol Grit dog wrote: Also, your toilet leak, is it the supply line/valve dripping? Where it goes into the toilet. I had a drip there this year, appeared to be the valve leaking, replaced it and then found the connection was just loose. (Looked like it was coming from the push button end of the valve though) Yes. There are two hoses. The leak is dripping from one of them. I honestly didn't spend a lot of time looking at it, but the hose is clamped to a plastic fitting and it appears to be leaking at that connection. It didn't feel loose really, but maybe the clamp needs to be tightened down and/or more sealant applied. Other than taking it out to practice in reverse next weekend, we don't plan to use it until December anyway, so I just left it for the dealership to deal with. I'll just ask them to prioritize that and the furnace fan issue in case they can't get to everything on the list before we need to take it back for our trip in December. The furnace noise is concerning, because it sounds like something is rubbing on the fan blade and I'm worried it is a wire. I took the panel off to try and get a look at it, but can't really see without taking the entire furnace out. By the way, are furnaces typically propane only, or can they be run off electric when connected to shore power? The fridge does this, but unsure if the furnace will too. Also, the furnace just seems to be sitting loose in it's cubby. Are they supposed to be bolted down? I was kinda surprised to find that it's just sitting on the floor not fastened to anything.Re: ProPride and lifted 3500 MFL wrote: OP...not sure which Dewalt pancake you have, but mine will get to 165 psi fairly quick, and capable of filling your tires easily. It is also lt wt, about 35 lbs. Mine is very similar and it will do 80 psi tires if I let it run between tires. It's just kinda bulky and don't necessarily want to haul it around. I can certainly fill my tires at home, but not sure when on the road. I found a product called Viair that are fairly compact that can do it, but they are like $300.Re: ProPride and lifted 3500 Grit dog wrote: Apex, Trust your gut here and don't let the others over-complicate this for you. You pulled it, it handles good, end of story. Next step is tow it somewhere to enjoy some time with ZERO worry about your truck doing the job very well! Agree. Initially I was pretty nervous about it, but I got the WD set up and the truck seems to have no problem pulling it. I've been up and down from Phoenix to Payson and it performed great! My only worry right now is backing the thing up and getting it through the 10' gate where we are storing it lol. But practice makes perfect. We have a trip to a KOA RV resort in Tucson planned in December and we're excited for that! I also have a minor leak at the toilet and a weird furnace fan noise that I'm bringing it in for in a few weeks. By the way, I'll need to air up the tires. I have a DeWalt pancake compressor that can fill up to 80 psi (barely), but are there smaller portable compressors that can do this? I don't necessarily want to carry a heavy compressor around. What do people do to fill their tires? EDIT: Attached a pic of the truck (with kiddie tires) and trailer. I'll get one of both in a week or so. Re: ProPride and lifted 3500 BenK wrote: Since lifted and higher CG, hope your track was also increased significantly with aftermarket wheel offset. That lessens the tip over point or angle. Hope your lift system has double shocks and increased torsional rate anti-lean bars. Higher durometer anti-lean bars as noted by BackOfThePack is also a good idea if you haven't already (Delrin would be my choice and suggest staying away from nylon types). Some lift kits has blocks that are angled to point the diff U-Joint upwards. Bad and will wear out that U-Joint quickly. Both output shaft and diff pinion shaft center lines MUST be parallel no matter what changes to the Z height the lift introduces. Stick with square blocks. Fun stuff and enjoy your setup ! Don't think the lift came with anti-sway bars; at least I think that's what you mean. It's a suspension sub frame lift with torsion bar adjustment and square blocks in the back (not angled). The wheels do widen the stance by about 2" on each side. Going the speed limit, and even under during 75 mph limit stretches, I haven't felt like the truck is leaning too much around corners. I also reduce speed down to caution sign recommendations. It's a 4" lift going from 33's to 35's. It's not extreme. But I also acknowledge it still raises the center of gravity and I just need to go a bit slower than I would otherwise. I once towed a popup camper with a Tacoma without WD and THAT was sketchy. With my current truck, I don't feel any slop or drift in the steering. It feels fairly well planted. Anyway, it's the truck I have and it's the truck I'll have to tow with.Re: ProPride and lifted 3500 Grit dog wrote: @ApexAZ. Yeah, just enjoy your camper. I'm sure it tows as well as you claim. Now lets see a pic of that heavy hauler all hooked up! The rig is currently parked, but we plan to take it out the weekend of 11/6 to practice backing it up and parking it. We found a nice big open gravel lot not too far from home where I can set up some cones. I also need to take it back to the scales with the toy loaded to get another weigh in and tongue weight measurement. I'll snap a pic then. Stay tuned!Re: ProPride and lifted 3500Thanks for the long, thoughtful post! I consider myself to be a pretty good and safe driver. I have not been in an accident since I was a teenager back in the 90's. It wasn't until I started riding a motorcycle in my early 20's that I really learned how to drive defensively, but it carried over to my regular driving as well. To the point that even when driving my truck, I get annoyed when people pace me in my blind spot when they have plenty of space forward or aft , not to mention the fact they are clogging up the fast lane. So while I'm not very experienced with pulling such a heavy load, my defensive driving is way ahead of most others on the road. The fact that I even came here seeking advice should tell you, and others, that safety is a top concern of mine. I can't revert my truck lift and trying to buy a new truck proved difficult given the current supply chain issues. On the other hand, I live in Arizona and like my 4 wheel drive with kiddie tires and lifted it accordingly. I also knew that I wanted to tow a travel trailer, so I didn't want to go to extreme height either. I can't afford both a truck and a dedicated 4x4 vehicle. Nonetheless, I have towed the trailer and it feels pretty solid (not that I have much of a baseline to compare to). Even in wind I haven't experienced any sway and steering/control don't really feel all that different to me. Big RV's and trucks passing me in either direction on a 2 lane highway have no effect whatsoever. I don't even feel it. I will say the braking distance is a bit longer so I have to start braking earlier than I normally would. Also, the truck is a lot stiffer under the load and we can really feel the bumps a lot more. I assume this is to be expected. I'm not sure what booster shots or face diapers have to do with anything, other than maybe it relates to risk management and public safety in general, similar to driving? It seems off topic overall, though. Thanks again for your thoughtful reply!Re: Trailer Bounce oscillationsMy previous truck was a 15 GMC 2500 that I did just a basic cognito torsion bar level with longer UCA's and Icon shocks with external reservoir front and back. That truck rode REALLY well, but I never towed anything other than a flatbed with a SxS in back. This truck I have a 4" CST suspension lift (4 in the front, 2 in the rear) with the Fox 2.0 pro shocks and it rides terrible compared to my 2500. Any washboard type bumps are incredibly jarring. I'm not sure if it's the shocks, the lift itself, or both. Could partly be from going to a 3500 from a 2500 too. Maybe it's just stiffer all around. It's even more stiff with the toyhauler on it, but I suppose that's to be expected when you have all that weight compressing things. But yeah, other than the rear end oscillating up and down a few times over larger bumps, the truck seemed to handle it fine. I averaged about 63 mph, but got as high as 70 and never felt like I was fighting for control. Handling, braking and power all felt really good. The tow mode seemed to keep it in low gear going down grades and the exhaust brake really helped keep the speed under control. I feel much better after towing it a good distance. High cross-wind will be the next big test I suppose.
