You would think the manufacturers would get with Ford and work this out on the chassis prior to delivery to the MH manufacturer. It's not like they don't know what's going on the chassis...equally, it's not like they don't know the majority of owners end up doing something to make the handling tolerable. The manufacturers will build the most they can and stretch the weight limits to the max. Ford understands this and should build the chassis suitable for the purpose.
