Actually; they were a lot of fun; with a more modern power train, fuel injected small block, strengthened frame, better front axle (even a late narrow D30), more modern rear axle (easier to get lockers), gears for the (modern) mud tires 4wheel disk brakes and more comfortable seats, modern shocks, etc....
No problem on the highway, in summer, can be cold in winter (no heater).. Slow in stock form due to the 5.38 axle gearing... I especially liked the hand cranked windshield wiper. My feet are too big when the Jeep is equipped with hanging pedals though (had to drive with my toes).
Enjoy!
Edit; that one looks like it might have been made for the Navy because it doesn't have a tail gate.
