I loved that show and thought the same thing. I believe the Raptor could make it threw, but it would suffer serious damage doing it. For sure you would need a superior bumper with winch, sturdy rear bumper with high lift points, 37" tires or larger, skids, armor and a shit ton of spare parts and recovery gear. Not to mention shocks, springs, snorkel, constant air, welder (we are talking Alaska)... and I wonder if the diffs and axles would be able to make it the whole way because that mud was pretty crazy at some points. But as the OP asked, yes, i believe it could be done.
