For any future members curious, the jeep did fine. I took I40 which I believe has less long inclines/decline. I believe I was a little over my ori ginal weight estimate of 1800 lbs (trailer is 900 or so dry). Probably closer to 2200 lbs, but since I have an LJ, I wasn't stressing (too much).
Just go slow and anticipate braking. Give yourself plenty of room to stop. I went about 60mph most of the way. I also have rockjock front sway bar and heims in the rear sway bar. The extra sway is noticable, but just go slow, take it easy.
Anyway, thanks again everyone
