I used to have a hitch-hauler for my wheeler. That worked awesome for my one man and two man shacks.
I even bolted a matching sled (two man Eskimo) to the hitch hauler. The shack nested perfectly into to it. For short runs I wouldn’t even tie it down.
I did however always have a strap running from the hitch hauler to the rear rack, to help distribute the weight.
B-man, forgive my ignorance, but is this (attached picture) similar to what you’re referring to? And you’d have that in your ATV receiver with the flipover on it?
