Awesome! I'm a fan of the exterior shots as well. I am definitely getting some more aggressive treads on my next set of tires. Did you shift through any lower gears during the climbs and descents, or did the Jeep handle it all in "D" only?
I think that with Jeep's weakest 4-wheel drive is set of tires with a decent grip a must. Regarding your question.. Almost all of my off-road driving is on first gear with traction control turned off. At the beginning I was trying to go with TC on but I found out that TC was somehow too aggressive and I like to have 100% throttle control under my right foot ;)
