Lateral weight difference
I just weight the bus at a weight station. I weighed each wheel and have a difference side to side 200 – 600 lbs. depending on the axle.
I don’t recall reading or hearing a “Max Difference” in weight.
Of course one would want to try to get each side as close as possible but
when that is not realistic what is the suggested difference?

Wouldn’t it be nice if each side of each axle carried the same load?
In a perfect world it would, but it starts with converters who try to do just that and get close. But generally it is not likely to happen because of a wide variety of factors. On my coach all my fresh water is on the passenger side and as I use water those 800 plus pounds move to the holding tank on the other side.
Then there is the problem of what we load in the bus. It may not seem like much, but by the time we add food, linens, clothes, spare parts, tools and everything else we put in the coach when we get it and it is empty we are influencing not only side to side balance, but axle weights.
Maybe buses of the future will have moveable ballast that is controlled by the chassis multiplex system that moves weight side to side and which adjusts air bag pressure to load or unload axle weights.

I don’t think 600 lbs is a concern Larry, I’ve heard of 1000 or better on some conversions.

Jon: if you have 200 gallons of fresh, it weighs around 1,600#.

Except I move about 100 gallons because I don’t carry anywhere near 200 and I don’t ever drain the water total contents.

Tom, thanks, I have to dig out some old info I have somewhere.
It was from RV Safety I think, from one of their weighting events at an FMCA rally.
One of the problems of “maturity” is I have All this unconnected info floating in my head.

CRS Larry, I’m right there with you…

Unless someone is carrying excessive weight (such as Tom carrying dues money) the weights are what they are. Whether they are out of whack side to side or over the axle limits the only reason to know them is so we know the correct tire pressures based on the weights.
I know of several coaches that exceeded axle limits by more than a ton, and as unfortunate as that situation is there is nothing we as owners can do about it other than making certain the tire inflation is based on the weight.
