Hmmm ???? Travel cover...
How about a snap on Tonneau cover like the pickups have ... seems to work for them ... Maybe something that would flip over the side or back and make an awning of sorts ... ???
OUCH !!! Almost 700USD for a Softopper (8' bed) ...
Not bad really in the Truck world (My fiberglas Camper top set me back about Twice that much) ...
... Not bad really if you're spending several K on a Nice TD ...
Thinking some of the more talented/creative members might want to make their own ...
