Finding a full sized truck that has been turned into a crawler is pretty common we would say. Normally you would see those Yotas out on the trail and think nothing of it. GMC on the other hand is normally not a truck you see crawling more likely to be found in the mud. We like to pick sides and think that Toyota is the truck for the hills. Someone had to prove us wrong by showing us this clip, a GMC making serious ground on this crawl.
