Motor delete\r
Radiator delete

This was my dad's camper that he bought like this. The story I remember is there was a company that would build these, it's a combination of several vehicles. 1960s Pontiac hearse with a Chevy Impala steering column, I imagine the camper was custom made. My dad pulled the motor and radiator to out into Chevy trucks. As kids it was the best toy we could ask for. My brother wants to put a 350 small block In it and get it on the road again someday
