I see a bunch of these in my area, mainly used by hotels that have guest cabins spread across their properties, and by a couple handyman services in town that specialize in small jobs.
I've also seen one on the designated ATV trails here because they are under the allowable width. Talked to the guy driving it. He had put Suzuki Samurai axles under it and swapped in a 1000cc turbo'd side-by-side motor. I think he was on 29" or 30" tires. Also had a shell on the bed with a camping set up on slide-outs that he had built. Super cool and unique little rig.
