I owned a 1976 Allegro class A MH on a Dodge chassis, powered by a (I think) a 348 CI V8. The engine was a somewhat rare truck engine for 1½T trucks. Drove it from Indiana to Los Angeles CA and back, the only problem I had was blown exhaust gaskets. ...
Bouncing is usually worn-out shocks.I would locate a scale and weight both axles, 4-corner weights would be ideal. That tells if your truck loaded weight is balanced or the front axle is way underweight.
