It is very nice that your parents are letting you park there.
That looks like a 1979 Dodge class C. I had one just before I got my bus. I lived in the Dodge for a few years. It had a 440 cubic inch motor that got 6.5 MPG. The roof leaked.
I did like the fact that it was better insulated than my bus is. It also had a 4kw Onan generator. That came in handy when I would park in the boonies.
