I did a lot of research and measuring before I got my Jeep. Most everything I read said a 4 door would fit a pin, but a 2 door would not. I just planned on towing a trailer for pin hauling.
Turns out if you move the passenger side seat all the way forward, and take the back seats out, you can easily fit a pinball. You can't fit one flat, but if you put it in on its side (watch out for cabinet art) it works perfectly. I have a 2015 Jeep, so I don't know if this method would work for other years. I just wanted to put this information out there as a public service announcement.
