Simple box trailer plus air deflector on tow vehicle like
Transport trucks. If you have a roof rack on the station wagon, should be easy enough to do.
As for the drag inefficiency and trailer design, wonder if it's limited gain vs complex build.
Look at large transport design and the minimal aerodynamics. Ideological vs practical.
IMO, this is misguided. The goal of commercial over the road trucking is to move a lot of cargo efficiently. A big square/rectangular box suits palletized goods well, and the tractors will almost always be towing a trailer, so it makes sense to put the aerodynamic feature there, rather than cutting into the cargo capacity.
OTOH, the camper is a portable bed, so just needs enough headroom to sit up and lay down, plus space for "some" strategically placed cargo; and the TV will most often not be towing. Putting a deflector on the TV is just one more set up/take down hassle thing, and a waste of mpg when not towing.
