If you like the GMC... 59K Reasonable miles, one biz owner. I considered this van as well, spoke with Shannon at Four Way Auto and he was informative and professional with all my questions. May be good for a cargo conversion but I decided to go with a V10
Shannon willing to get it to local shop for your inspection, and seemed aware of the cost of Quigley conversion factored into asking price.
I also called Quigley about the installed system #8CQN012146G168 (2008) It has:
261 Chevy transfer case (think i got that right)
And of course, Quigley provides parts list and info packet to new owner
Owner Upgraded wheels 265/70-17
