The other thing to watch for in weight is left right balance. Many coaches are far enough out of balance side to side that you cannot counter it with your loading. For example kitchen and generator on the same side. My coach is within 100 lbs of side to side balance and which side is heavy depends on where I am sitting as I outweigh DW by 100 lbs.
Manufacturers do not publish those weights. You need a level weigh scale and some time to get the individual wheel weights or a State Trooper with a set of scales who is willing to be helpful.
