Don't let facts get in the way of a good story.The comments on this video are very misleading and exaggerated. The video claims the engineers raced up the dune and the JKU didn't make it, they were both bouncing off the bumpstops on the whoops and the JKU had it's laptop mount collapse, thus they stopped. We see newbies wreck vehicles daily through those whoops, we find coolers bounced out, front bumper chin spoilers ripped off, etc. The video stated that the JLU was high centered, wrong, they went over the crest of the hill and tried to reverse back to the crest (Which is a big DNR ticket if caught because that hill is directional, one way over the top). When that didn't work they proceeded forward down this dune.
They were at Silver Lake Sand Dunes for two weeks and I watched them for a little while daily while providing Jeep dune tours and in my own vehicles. Air pressure is very important on dunes and stock JKUs with correctly lowered air pressure were doing just as well as the JLUs being tested. The tested JLs even had a few days out there with what appeared to be street pressure, they did poorly just like any other vehicle would with too hard of tires.
