1978 La Palma RV (Casa Grande)

I inherited this RV when I bought a home so I don't know much about it--since the battery is dead, I havent been able to start it but it does appear to have an engine and AC unit on the roof.
It was transferred to the previous owner at like 59K or 69K miles so I doubt it has more than 80000-100000 miles on it.
It is free--you would just have to tow it away.
