When Jon spoke about the back bed of a pick-up it brought back memories for me when I had a 72 GMC Truck with a 64 slide-on over the cab camper. It used to belong to my parents. It was great for week end trips to the lake towing a boat or a week at Shasta Lake in N. California. I was 26 at the time and it was fine at the time but very basic. No A/C, water pump , bath or shower. Two people could not pass one another without one sitting down.
Good Times!
