My CJ-2A was responsible for both hemmorhoids and lower back pain in my youth.
The heater sucked, the brakes were weak, and it was underpowered.
I've ridden a hardtail Harley or three, and they're considerably more comfortable than that old boneshaker of a CJ.
Flying 12 hours in a low-level B-52H sortie, with wings flapping and your helmet bouncing against the ejection seat, will still shake you less than a few minutes in a Jeep CJ.
Now that I've retired and no longer need to "rough it", I enjoy the comfort and design of my new Liberty.
Hell, I didn't even know what Approach, Departure, and Breakover Angles were until I got this newer Jeep and looked up "Trail Rated".
