Hi Val and welcome to the RVUSA Forum. Other than the fact that it is 35 years old - if it has been well maintained and all the parts and appliances work, and you can get it for a good price, I'd say go for it.
Just remember, motorhomes are houses on wheels and when you rattle a house up and down the highway, things are different from a house sitting on a foundation. Things flex, rattle and break, but RVing can be quite enjoyable nevertheless.
Welcome to the forum and post back to let us know how you do.
