If I were you, I would buy some 3/4 or 1 inch PVC pipe, some fittings, and turn on the creative side of the brain. I made one that was basically two X's about 36" apart to cradle the fusilage keeping it off the landing gear. I don't have an XTerra but you can probably put a length of PVC between the sides of the cargo area and let the wing lie on the PVC rack and hang over the back seat. I hope that makes sense.

I just recently bought a Ford E-350 15 passenger van, removed 3 bench seats, and am getting ready to design a two tierd rack system for it. In the end, I should have enough room for a couple of 82" long fusilages setting of the floor and still have seating for 6.

Financing and credit debt ROCKS!
