The Tex Ritter version is much better. google it.
A few points to ponder...
That young gentleman first heard the story in the 1950s? He doesn't look old enough to have been alive then. I was, and I know what us old fogeys look like now. However, perhaps the video was made in the 1970s...
the young man is quite the cardshark. He stacks the deck quite well. As I recall the original recording, such deck stacking is not necessary. I could be wrong, though, it happens frequently.
It is, however, a truly awesome story, even if he doesn't do it quite the way I remember it.
He says he heard it from a recording made in the 50's, not that he was alive in the 50's.
Since the camper overhangs the sides of the flatbed, you could combine the function of a guide plate and tie down by pinning though a plate hanging below the wall straight into the flatbed side rails, or one that slips into a pocket on the side of the flatbed. If it was flared a bit it could guide the camper into place
I carry a 1 gallon tank in an exterior compartment I built into the wing. It's short enough that I can set it in the propane compartment upright (my camper uses a horizontal 20lb'er) and connect it to the camper line if the main tank runs out unexpectedly. That 1 gallon can make the difference between being cold and not :)
