Enclosed Car Trailer Buying Help!

I am curious to know what "ma Snart" gets for mileage with that. With my 2010 1500 and the v-nose 20' I average 10.5. That is with the 3.92s and air bag helpers on the back.

a lot of it has to do with the truck... my 4x4 is pretty tall stock so a lot of the frontal area is already blocked. as far as a v nose getting worse mpg that seems pretty hard to believe, I mean you think a brick is going to have better aero than a point?
