RE: Gas engine

Of course its worth more, because it cost more to start with. You can make the same comparison between a XL and a Lariat, guess what, the Lariat is worth more; because it cost more to begin with. So is there some meaningful point you are trying to make? EASE of selling. Reality my truck is worth at minimum 7k more than the same gasser. Actually the options don't add up to that much. The Sport package only added $350 of value and about the same for the LOW mileage.

RE: What should the PSI be in the trailer?

"I eventually figured out I need to buy quality tires to replace my OEM junk, but it did not happen overnight." I ordered my 15 RAM, I knew it would be coming with POS NEXXEN tires. So a month before my truck came in I went to Discount Tire and ordered 6 Michelins. At 200 miles i had them installed and sold the NEXXEN the first call for $650. I will be honest i only made 40k on that set of michelins but they credited me $600 towards ANY tire I wanted to buy. I chose the new and "IMPROVED" Michelins. So far at 24k they are wearing MUCH better than the last set.

RE: What should the PSI be in the trailer?

Load inflation charts give load limits for different pressures, they are not recommended pressures. Who said they were??? Even the tire inflations chart where it says MAX is NOT recommended. Inflation charts are there to assist you in running the tires at their best performance. Meaning BEST possible stopping, BEST possible ride and BEST possible tread wear. Tires are part of your suspension, they should be aired to provide the best possible ride and stay within the tires capability. 98 RAM 120K Michelins, 100k BFG's. 86 C20 120k Michelins and 80k on Generals. The list goes on and on. All it takes is QUALITY tires ran at the proper pressures for the load along with a GOOD alignment. Tires have a built in factor just like anything else does.

RE: Demco Recon 5th Wheel hitch

"I almost went with the Anderson but it was a newer concept at the time and I didn't want to be on the bleeding edge." I think you made the right choice. Their video showing downward force is a FARCE, if they did a fore and aft test like real world conditions they would have learned that it could quickly become a "Folding Hitch".

RE: Gas engine

How about this comparison. People always say buy 4x4 simply for the resale value. I say the same comparing Gas to Diesel. I paid 15k last Summer for a 2001 RAM Sport 2500 4x4 SRW LB with 123k original owner miles in great condition. What would that same truck be worth with a Gas engine? NADA clean retail with Diesel option $12,325, clean retail gas engine $7,250. But the fact is the RAM Diesels get an additional premium price.

RE: What should the PSI be in the trailer?

The issue with all this dialing in and weighing is that it does not give you any added margin. I don't want my tires to be exactly at their capacity. I want a bit of additional capacity or safety margin. When I hit a run of pot holes and rough roads I want my tires to be able to withstand the additional impact. My G rated Sailun's are up to the challenge. Aired to 110 PSI I have lots of margin to withstand the rough roads. MY E rated OEM tires were not up to the challenge and I ended up with blowouts forcing me to seek a better tire. G rated Sailun's aired up to 110 have resolved all my tire issues. No charts or individual wheel weights required. I had the same issue with my prior RV. The D rated tires were not up to the challenge, but E rated tires aired to the max resolved my blowouts issues once again. In the end you can weigh and air to match some mystical chart if you like but I will go with the max. PSI method. I am referring to RV trailers only. Most other trailers have totally different characteristics and aerodynamics, the max. pressure method may not apply Do you run your 4 rear truck tires at their MAX 80psi? Bottom line RUN QUALITY TIRES! I have never had a flat or blowout on a RVtire EVER.

RE: If money was not a issue

Don't have a spray on roof, it's rubber and I would not want anything else. I already have the other things. What I would/may do is change out my MORryde IS 8k to 9k. If anyone is going to be in NW WA this Summer and would like a deal on my 8k system PM me. I do have a Friend with a Metal Fab Shop that has a lot of Trailer experience that can do the RnR. Reason for changing is my axle weight is 17,500# and I would like better braking as my RV weighs 23k. Jettison LUCY's rocks!!!! Chris HA. It ain’t all her. I recently had to remove a few hundred pounds of things that go bang from my basement. The front had dropped a small amount so I hit extend and just sat ther with the hydraulic pump pumping away with no movement. :B

RE: What should the PSI be in the trailer?

Give GY Tech a call and ask them what to do when going from a "E" to "G" tire. They will tell you to use the chart and add 5psi. Why do you think they make the chart? MOST RV's axle rating is determined buy the tires capacity at MAX psi. Using that method on the LT235/85R16E to a LRG would increase the load capacity from 3042# to 3170#. The same method for a ST235/85R16E to LRG would increase the load capacity from 3640# to 3750#. As you can see, load inflation charts are not compatible between tire size designations. Not sure your point as it relates to what I said.

RE: What should the PSI be in the trailer?

Max pressure may be CYA, but I CYA'ed the heck out of the lousy "E" rated ST tires that came on my trailer" Most likely the tires had to be inflated to MAX to get the axle rating.

RE: What should the PSI be in the trailer?

The oem tires call for 110... I would be running 110 minimum.Why? If you're getting good wear patterns and no issues with running lower pressures why would you blindly follow recommendations that are based on "E" rated ST tires? "G" rated LT/ST tires don't show the "B-Ball" effect, their sidewalls are too stiff for that to happen. There's quite a bit of data that suggests there's no reason to blindly follow the "Use Maximum Pressure" suggestions. Good wear patterns, long life, not beating your trailer to death, all good reasons to run lower pressures on "G" rated tires. JMO of course, and I will continue to recommend that people with "G" rated tires experiment with air pressure until they find what works best for them. Hey there is the BLIND way to go thru life using the CYA method or one can actually use their BRAIN and do what is BEST for their situation. I prefer the latter. ;) Max pressure is CYA. I use the CYA method because I have suffered through the blowouts from the era when I did not use the max. Pressure CYA method. Again I do not want to derate the tire by not filling it to max. PSI. BY the way are you filling each tire to a different pressure using those charts? Are you assuming each wheel weighs the same and carries the same/equal load? You are supposed to weigh each tire if possible and air that axle to the highest weight. I run MAX on my DRV because I have a HUGE axle load. I run my ENDURANCE tires based on load on my Boat trailer. I run my MAXXIS tires based on load on my MC trailer (ENDURANCE were not available). If I were to run MAX the MC trailer would be bouncing down the road. I inferred all 12 of my tires at every stop and in ALL conditions they are running cool. Should I rum my DRW's rear tires at 80??? Do you ??? My truck placard says 65 for full load, I run full RAWR so I run 65 as the weight/inflation chart will also tell you.

RE: Demco Recon 5th Wheel hitch

The part of this setup that is NOT good is the head pivot point is below the kingpin connection height. The offset appears to be less with the Demco than the Curt that is known to cause chucking with several inches of offset. Looks like a good solid setup. Negatives are the pivot point height and the typical loose connection of the Standard Rails. You would have to buy 21k rails to get the full 21k rating, not sure who makes those??? The pivot point of the B&W hitch is at the same height as the kingpin connection.

RE: Auto Leveling

"I agree the jacks can handle the weight but can the frame? Can the frame withstand being supported across an increased span? " I don't have an issue with that. My frame is a stacked box tube frame. Two 2x6 tubes stacked and welded to a 2x3 tube making my frame 2"x15". Never heard of a frame jack related issue???

RE: Auto Leveling

I built blocks for our setup for more stability and also the fact we have 3" risers. I hit AutoLevel and it does it's thing. I get a kick out of not wanting the suspension hanging comments. The fact is the system is designed to that without issue. Imagine the wheel touching but if the rig were to be raised 1" it would be off the ground does it make it better that the tire is barely touching? https://i.imgur.com/dJFCFPGl.jpg https://i.imgur.com/8HJ1Okdl.jpg https://i.imgur.com/iKKfsYyl.jpg https://i.imgur.com/m1hQv1Cl.jpg

RE: Gas engine

"Two possibilities of that, solo at 104mph or towing into a head wind of 40mph at 75 mph." Yup...solo at 104, seems we both have great memory function!:) Actually, my barely over 7 mpg, and combined wt guess, was double tow, including my bike trailer, with 2 bikes (short 1K lbs). Jerry The day we left Rolling Retreats after ordering our current DRV. We were Westbound on 40 bucking a headwind of 40mph. We were in a BIG hurry to get to AZ for some warmer weather as it was the second week of January. Notice less than 200 miles on a 35gallon tank. https://i.imgur.com/MynR8bxl.jpg

RE: What should the PSI be in the trailer?

I have a trailer which has Sailun G rated tires. The maximum PSI of air is listed as 110 PSI. I was carrying 90 PSI but recently was told that the maximum PSI, that is 110 PSI is the amount of air I need to carry. Which is the amount I should have in the tires? Look on the side of the tire. The max PSI number is on the side. I run the max psi when I am towing and then run 65 non towing. Why do you let the pressure down when parked? They still have to support the weight. I don't understand what there is to gain. B.O. He obviously mis read the post and thought the OP was referring to TV tires.

MOST RV's axle rating is determined buy the tires capacity at MAX psi. E rated tires are rated 80 PSI max. Adding 5#'s will give you 85PSI. I don't think 85 PSI gives me the maximum cargo capacity,ability, performance of a 110 PSI tire. I prefer to skip the charts and go straight to the max. I do think it's a good idea to monitor the wear for the B-ball effect as mentioned in JIMNLIN's post above. WHERE did I say anything about adding 5psi to an "E" tire??? I DID add 5psi to the chart for the "G" tires that made 85psi the correct pressure. Many thousands of miles with perfect tread wear and cool running even in temps North of 100.
