OP, the suspension on nearly all bumper-pull RVs and 5th wheels is state of the art directly from the 1920's. VERY rudimentary. It's one of the major causes of tire failure.
Just because it's been around a while, doesn't mean it's bad.
Your heavy duty pickups all use leaf springs. I think only Dodge has tried coil springs on the 3/4 ton trucks (1 ton they still use leaf) and there are mixed thoughts on that use of more advanced technology.
Typically failures can be traced to...road debris, overloading and/or low tire pressure. Do you have any documentation (not anecdotes) that leaf springs are the cause of tire failure? I've never heard that before.
