Phil, I think you are right, on weight distribution, I have long believed that each tire should carry the same load for the MH to handle correctly. I am sure that WB/L ratio helps but is already great on these 24 ft MH's and these other add ons help. On my current MH each tire carries aprox 2500 lbs. It is a P-30 chassis that many on this forum complain about handling issues and a white knuckle ride. The only add on I have is a steer safe, and it makes no difference in handling. I drove it 500 miles without it and saw no difference. I drive this MH with one hand like my car. I never hear any mention on here that each tire should carry the same load, but this is MHO. The only problem I have is I can't find this information on the MFG web sites. I don't know if you guys have found a way to estimate this other than weighing the MH at 4 corners.
