There are plenty of non stock trucks here. I have a V8 in one and the other is a 97 converted truck.
You will not receive bad advice from people here. If you want bad MJ tech go to Cherokee Forum or Facebook.
You will also not receive advice on towing a car on a trailer with an MJ. They are far too light and the toad will push it off the road.
If you want to tow a car get a real truck.
Have a nice day. (There is your friendly reply from a mod)
