Or you could do it the other way around -- boondock in a small travel trailer and use the truck as a tow vehicle/cargo carrier. That's what we do -- and we boondock in some pretty remote and sketchy places. (If you have a little time, check out some of the boondocking entries in our blog -- the link is in my signature.)
Having said that, I can't deny that a TC can go places that my trailer can't go. We park the trailer on the edge of too sketchy, and take day trips with the truck into the really difficult places.
