Last week we went to Hidden Falls Adventure Park and had a great day jeeping the trails. That was not the problem, the problem was getting there and getting back home. We were pulling a small teardrop trailer that weights about 1000 lbs. The jeep spent a lot of time downshifting and at one point went all the way to 2nd gear while doing 65 mph in cruise control. So, seeing as we have a sizable trip going from Houston TX to Virginia and back next month, I decided to remove the 3.21 gears and install G2 4.11 gears, reset the computer and go from there. We are running 31.5" tires with an automatic. I believe this will be an answer to our trailer issue. Down the road, we will install 33.3" tires and that should be fine for daily driving and trailing. But when we are trailering, we will go back to the 31.5" tires for a better pulling gear. We are still stock except for we leveled it with 1.5" spacers in the front. That made a huge difference. We will put a 2.5" lift in it in a few months when it cools down, too hot here to mess with it right now. End of update.
