I have an Overland without the towing package, and decided to see how it towed directly from the bumper. Dremeled out the lightly marked hole, threw a 2" ball and torqued it down. Towed around 1700-2000lbs on a single axle trailer and it went surprisingly well, especially considering the ball...
Whoops, I am yet another who posted in Midwest, only to find out I'm in the Great Lakes area!

Got my JT Overland 3 weeks ago and love it to death so far!
