Finally thought I would post in this thread. These were on my recent trip across Utah, including Arches, Moab, and Canyonlands. Elephant Hill in Canyonlands makes Hell's Revenge seem tame...
I was on the fence about the Silent Armor's vs the Duratracs, but after this trip I am stoked on my SA's. They did everything that the crawler jeeps did (in wet conditions on the trail) and then were smooth and quiet getting 19.6 MPG on the highway.
Also, this was my first "hardcore" test for the 5100's and ProComp springs. I was impressed, only whacking the back end of the receiver a few times.
Next purchase is definitely a front winch bumper, I got some looks and questions from some jeepers at the trailhead, and definitely found out why halfway up the hill when the rain started falling. WINCH!
