Those campers are mfr'd by Livin' Lite
. They are still advertised on their website. You could contact them and request a locale for one, or go to your local Jeep dealership and have them research for one. The dealership may have a better database of info than the mfr. You never know. But I'd figure you'll be paying a lot more through the Jeep dealership. There are 2 Jeep models too.
You can use the CL search engine
to speed up the finding process.
I'd prefer their 6.0 model (Jeep is based on this), and mod it for my tastes. They now offer a 6.0 Offroad model.
If you are looking for the jeep offroad trailer that has a roof top tent, there are several mfrs out there. Dinoot Trailer
is putting together several model trailers and lots of options for the buyer to choose to fit their requirements.
