Bumpy how bumpy is your bumpy road?
The Chevy P series chassis does not have to be rebuild to be decent anymore that you have to rebuild a rubber roof MH with with fiberglass roofing materials for them to stay dry.
At year 18 our 1992 P30 MH chassis front coil springs sagged so the ride height was too low even with 100 PSI in the leaking air bags. For the same price as new OEM coils and new air bags installed we did loose the air bags for good and upgraded the chassis by going to the
Henderson SS coil springs. Some of us would not have ever had a MH experience had it not been for the P30 454 MH chassis and EPDM rubber roofs. Please do not post your opinion as a fact of life and confuse good people hoping to offer their family a MH experience the best way they can.
A MH with P37 in the VIN is not built on a potato chip truck chassis but one designed by GM for the MH industry. While they share a lot of parts they are not the same as under a potato chip truck of the same era.
If anyone buys a GM, Workhorse or Ford MH chassis and expect the ride of a diesel pusher chassis then that is another store.
