Here is my Terra 500 camper I imported last year. I've been doing a lot of work since importing it, namely gutting it and fixing things as they come up. A lot of these Elf's have a split ring rim so I made a video explaining how I've put new tires on mine

Here is another fixing up and repacking the Aisin locking hubs and a 4x4 test here in Maine

Hope these will help if you have the same job!
