This might seem crazy but for your extended trip having off the ground sleeping could make the trip FAR FAR more enjoyable. You might consider adding a cot to the list of things your taking. I've spent 15days sleeping on the ground after about day 12 you feel as if your really not getting any sleep the cot would seem like heaven.

Skip the cot and try an air bed. Super-comfortable! Just need a transformer to supply you with 120v off your 12 outlet to run the pump.
