class c

I recently purchased a 1979 ford Vanguard class C and I'm looking for the owners manual for the ford vehicle that was used in the conversion. I've searched endlessly but unfortunately Vanguard is no longer in business so it's become very hard to find information on their older models. Any help...

My mom and I are thinking about RVing in the future (with an RV already in mind) and we'd like some information on how the monthly payments work for the parks. We know the parks require a deposit to hold the space at least 2 months in advance, but what if we don't know what the park looks like...
