I think I can run some ratchet straps between Serenity (the camper) and the fuel cell (the spare) and around the outside of the ion propulsion engine (the obsolete George Foremen grill) which will enable me to support the weight of the IPE on the hitch platform somehow.
After I wire up some extremely low output LED'S via the rear light circuit on Serenity into the inside of the IPE I will be able to go into hyperdrive with a twist of the wrist in the bridge.
Boo Boo thinks it just might work:
