OP, yes you will get better mileage. You will go from 7.8 to around 8.0. And that's if you tow in the mountains a lot. :)
No matter what people say, V trailers, spoilers, air tabs, wings and the such are not much use. Wind is very sneaky and very counter intuitive and wants to do it's own thing.
If you did aero tests on a wing on an SUV or truck you would find out that the wind gets pushed over and around the wing and then immediately wants to fill in the void of the vacuum the wing just created.
Also the underside and back of the trailer has just as much or more resistance to air than the front. That's why you see a lot of long haul trucks that have side skirts now. Even then it's very little help. But if they pick up a 10th of a MPG and the company has 500 trucks on the road that can add up pretty quickly for them.
For the average RVer, not so much. On my vacation this year I traveled 5,700 miles. Even if I saved a miracle of 1 MPG with a wing or whatever I would have only saved about a tank of fuel over the 5,700 miles.
There are a few V nose trailer sites out there on the WWW. If you go to one I'm sure they will all confirm what I told you about the mileage.
