We'll since I build and own 4X4 Vans and have taken mine many places you wouldn't think a van can go, I think I have a pretty good idea of what they are up against. I've also won the Baja 1000 in Stock Full and owned a Stock Full truck, so I have a little idea there also.
I've looked over a new Quigley IRS Chevy pretty thoroughly also, and while very nice it is not Baja Racing ready. Unless this van is significantly different than their regular Chevy offering it won't hold up to the average speeds that they will need to carry to finish on time.
I've got thousands of Baja miles on my Dana 50 TTB FORD E350 and it is a much better Baja suspension system that has been tested and improved for cause after extended Baja miles.
There is some video of us bombing down the road to Coco's on our website.
Don't get me wrong, I'd like to see them do well - just being realistic.
We're leaving for Baja in our Van in just an hour - I'll be watching for them, and willing to lend a hand.
