I have winched campers onto flatbed tow trucks (impounding abandoned ones usually).
If I were doing this one that way, since it’s sitting up on stands with no easy way to lower it, I’d back up to it and tilt the deck so it went right up under the front of the camper, lift a little with the deck, and remove the front sawhorses/supports. Then I’d winch while extending the deck out, so the camper stayed exactly where it is but the truck deck slides under a bit over half way.
Then just winch it the rest of the way on.
Run the straps around the back of the camper across the rear corner jack brackets, so it doesn’t crunch when you pull on it. And set some wood under the lower leading edge of the camper so you don’t grind it up. I always already had 2 or 3-foot pieces of 2x10 with a strip of 1x4 screwed across one end. Put that under something being dragged on, the strip of 1x4 catches and keeps it from sliding all the way under.
If you call for a tow truck, I’d suggest having these already made up in case you don’t get the world’s greatest operator.
I wasn’t going to suggest this because unless you have a buddy in the biz, the tow bill might be more than that camper is worth.
It appears to be just a little 8-footer. Any half-ton would carry it home without issue, and a single axle trailer would do it too. It’s not that heavy.
