No progress on my side. I got distracted from this idea with the idea of converting a Ford Camper Van I bought to 4wd. It was a great plan, except for the lack of time, lack of fab space (and skills), and the ability to justify the additional investment of money into that thing.
I've since sold that project, and am now back to my idea of buying a cheap pop-up and building an off-road worthy frame for it.
I still like the idea, but I got off the Runner Flip-pac project based on concerns about space. I love my Runner, and it is already built for off-road, but the platform is just too small to make a useful camper IMO. The Earthroamer Jeep platform is what I had in mind to emulate, but it is really small. Too small for 2 adults and 2 dogs, and God willing, kids in the future.
I'm now thinking a trailer better fits my needs/wants. Could change tomorrow.
Good luck to you. And by ALL means, post pics if you make any progress.
