I think the Suburban would be my first choice, but my second choice would be a Jeep CJ-7. Other vehicles that fit the criteria, but would not be high on my list are the S-10 Blazer, Bronco II, CJ-8, Willys Wagon and International Travelall. Another vehicle that you may want to highly consider is a 1970's Dodge 4x4 van. They are out there and they do exist.
