Thanks everyone. I wheeled Kelly Flats outside of Ft. Collins yesterday. It's pretty funny wheeling a truck on bald 34s in the rain with an open rear diff, but I was able to make it through the trail with no real issues. I have to admit, I used to think that half doors were just for looks, but the extra visibility was really nice. Kinda reminded me of being in my runner with no doors, except I didn't get all the mud spray. Was about to take some pics, but forgot to put my memory card in the camera, oops!
