Old-school 4Runner. I always point people in this direction when they want a jeep. Reasons a 4Bunner > a jeep:

1. Much more reliable. The 22re has just about the best reputation of any motor out there.
2. Better milage
3. More interior space for people/cargo
4. The top still comes off for summer panty-cruising
5. Better than Jeep off-road in stock form (more stout, less tippy)
6. UNLIMITED off-road potential if you want to go crazy. Some of the best rigs out there (excluding buggies, basically anything that is still a truck) are toyotas.

Getting one without rust, however, might be a challenge.
