Hello All,
Just curious if anyone has measured their coach and see if it sits level or one side is lower than the other. Not inquiring about loading and moving around cargo, just a basic generic question. Have a friend that is getting a leaf added to his low side to aid with this issue. Never thought about this before and am curious what you all know. Also if you have had your coach weighed at 4 corners, what is the largest difference between points in pounds. My left rear (full wall slide side) is 540lbs more than the right rear. Sounds like a big difference to me.....just thinking out loud.

LF=3440 RF=3720
LR=7340 RR=6800
Total Weight is 21,300
24k chassis
Thanks!
 
Not apples to apples, but here are the weights on my Ventana (a few years ago)

LF 6810 RF 6490
LR 8100 RR 8320
LTag 4080 RTag 4120

So I guess 540 difference may be more than "normal", but I am no expert. And it's hard to compare a gas to diesel.
Any other gas units out there?
 
I made myself crazy on this topic as I had a significant difference (+500 lbs) more on driver side versus passenger. I spent months rearranging everything and got nowhere. Even Newmar said the following as I was pressing them for answers. Basically they said don’t worry about it.

I hope to ease your fears as there is a lot of misinformation on the internet that can drive a person crazy. For starters, Newmar has probably the best balanced RV’s on the market. The numbers you gave are not that concerning to me as, the rule of thumb for front axle difference is 1,500 lbs. between the two, and you’re well within that tolerance. With the numbers you’ve given, there should be no concern for flipping a coach due to a blowout. You would certainly want to up the tire pressure on the side that is heavier but other than that, I wouldn’t be that concerned. I have seen brand new coaches from other manufactures with up to 5,000lbs. heavier on one complete side.
 
Ours have different weights as well. I think it sits down more a tab bit on one side that the other. I am not worried about it. There is not such a thing as a totally level RV period, and I don't care who make it.

Everything I've ever read about tire pressure says all tires on an axle should be at the same tire pressure; and you set them all to the weight that supports the heaviest side of the axle.

On my '15 CS 3921 the drivers rear duals had about 600lb more on them than the passenger side duals when empty. The FWS is a lot heavier than the smaller bedroom slides so on a 2 slide coach you can really see that difference. I just made sure as I picked what I was loading to try to put heavy things on the lighter side. By the time I had the coach loaded I had offset about 300lbs of that factory difference. The coach never felt unlevel or drove poorly from that side-to-side difference.

On my '19 VT 4310 it left the factory almost even side to side (17805 vs 17775). But on any given axle there was a fair bit of a difference. Here are the factory weights:
Steer DS: 6065 PS: 6410
Drive DS: 7845 PS: 7325
Tag DS: 3895 PS: 4030

So I'd set the tire pressure to the right PSI for the higher weight on the axle, try to keep them close by loading heavier things on the lighter side when you have a choice. If you start seeing the difference exceed 8% or so then maybe you start to worry (the factory differences above are all under 7%). Make sure you get weighed when loaded for a trip.
