Here's some videos from my most recent Colorado trip...
I have a '98 TJ Wrangler with 35" tires, 6" long arm lift, 4.56 gears with lockers, 5 sp, 4:1 crawl kit and a bunch of other stuff.
In one video you'll notice a couple of old Dodge Power Wagons that are cool! I followed these guys up the trail. Now, those guys can crawl.
