I moved up to the GC Trailhawk. Mostly because I tend to put 24k+/year on my daily driver, but the WK2 TH is the right compromise between road manners, and getting over/through the washout that's in your way.
Drive what you like, and works for what you do, that's what I try to believe. Who cares if it someone doesn't think it won't work for them!
I imagine the MPG, and the road manners will help a lot with this trip. Look forward to some pictures!
