Pretty much anything that has 4x4 can e used for it. Ive even seen people take Lexus GX470's and fit them with steel utility bumpers, tire carriers etc.
Built and engineered here in Phoenix, AZ. Dedicated overland trailers of differing capabilities and amenities. They appear to be of high quality and packed with features for going off the grid for a few days.
