A ladder. Tie it on top of the truck or camper to get it there. It sure simplifies putting up a meat pole, hanging quarters, or whatever.
I have a stock rack on my pickup to haul my llamas to camp. The ladder goes on top of the rack. It weighs nothing and only adds 4" to the height.

“In a time of deceit telling the truth is a revolutionary act.”
