A friends dad put one on his stock TJ bumper and tows it from Cincy to Louisville regularly (2-3 times a month) to use around his property. It's a uhaul one and its pulled at 70mph up and down all kinds of hills and through maybe 25 miles of back roads that are fairly windy. His jeep is still in one piece. I've never looked that closely at how it's mounted but its wider then the frame I know that and the mount are near where the euro plastic bumper things are.
