'87 ford 350 suspension question
So my wife and I have just bought ourselves a 1987 ford econoline 350 jamboree Rallye for $1500. This is out first RV so I am just beginning o learn the myriad of things one must know about owning a MH. Out first and only real issue so far is that the front and probably back suspension needs replacing. There is a considerable amount of bounce when you drive over bumps and dips in the road. So my first question is: stock vs mod. I've seen a lot about air suspensions, but don't know if the conversion is possible or even desirable. Also cost is very much a consideration, and I am looking to do as much of the work myself as possible.
Any information, tips, or suggestions are appreciated, and I'm sure I'll come up with more questions as time goes on. Thanks
