Proud new owner of a rpod 193

I would go for that idea. It would make this less of a guessing game.

Ok, let me add something here that isn't some type of formula, that produces a number nobody understands, and then leads to different conclusions by everybody. I already tow a 195 with my Frontier. It's the exact same camper. I haven't had any problems traveling the east coast from the Canadian border to New York city area, and as far west as Iowa. I would not hesitate for one second to hook up a 193 to a Ford ranger, Colorado, Frontier, or Tacoma. The fuel economy is going to be as low as 9 - 10 Mpg, or if your lucky, 14 - 15 Mpg, no matter what you tow with. 

Well I didn't see the OP ask if someone could explain what frontal area is, and could we please discuss it to nauseam. You could take your own perfectly good advise and ignore MY post if you don't like it. I was trying to answer the question, not complicate it. 

I just eyeballed our trailer and truck.  The part of the trailer that is not behind the bed is about 7'x6' and is sloped like the curve on a pod.  I guess, worst case scenario, I'm under 50 sq.ft. full frontal ....ity.

Nope, it's not clear, at least to someone as slow as me.  But then I rarely drive fast.  The back of the truck is 6' wide and 4.5' high to the top of the tonneau covered bed.  The trailer is 7' wide and about 8.5' tall with the same curved front as an r-Pod.  There isn't a lot of trailer showing looking at the truck and trailer combined from the front.  And there are no cantilevered wheel with phenomenal wind resistance sticking out the sides.    So what would be the Cd x A?
