It's very frustrating to watch, I too wish the 2nd gen's would pick up the pace some. I'm convinced it's the best built rig on the show.
Anyone else notice the lack of lockers? Maybe they are not using them much, but it's crazy to be out there without working lockers.
They noted some form of traction aids in one or both axles in most of the trucks when they briefly and poorly showed vehicle specs.
That said, I'm taking said specs with a grain of salt because they also said the CJ had 44" tires (actually 37", the max size for the "competition") and that it had "two transmissions" (it's a SM420 w/ a Ranger overdrive unit).
The D90 is presumably locked f/r with ARB's--they appeared to be unocked when it got "stuck" in the sand...but you could see all four digging when they were winching out. More manufactured drama...
