While not a completed build, Cargo Craft in Corsicana, Texas offers these off-road themed trailers, and I'm really taken with the idea. A neat base to start from for anybody needing a small toy hauler camper, especially for a smaller tow rig.
Here's a previous post that has my build using a Cargo Craft made here in Georgia, custom ordered to my specs, and has a video for one of their Texas built off-road trailers, and plenty of discussion perfect for your ideas.

Edit: R&J Trailers in Dallas, TX has (and can get) the Cargo Craft "jeep" style trailer. I'm confident they will speak "our language". You could work out the details, then fly and buy or just get it loaded on the next transport to Phoenix!
