My first RVing experience was in 1952. I was 6 years old. My folks had just bought a '52 Oldsmobile and borrowed a friend's homemade teardrop trailer. My Dad had finally earned 3 weeks of vacation time, so we headed west from Cincinnati. First night I remember was in the Badlands, and the final stop was in Custer State Park. About 2,000 non-interstate miles in 3 weeks.
My Dad was re-living his youth. He and his best friend graduated high school in 1926, stuck out their thumbs, hitchhiked and walked as far as Montana, working on ranches for room and board along the way. He told me some stories, but I'm pretty sure he didn't tell me all of them. ;)
