RV wind deflectors????????

[zell66]

Looking a purchasing a wind deflector to place on top of my 08 f-350. In doing research I have seen many pros and cons to doing this. I would like members with REAL WORLD experiences tell me about before and after use. Was MPG improved? If so by how much? Also wind noise tolerable or not?

Thanks

That is why I am asking. We are taking some longer trips and looking to get better than 8 MPG

I'm not sure the benefit of a wind deflector. Seems most trailers already have streamlined nosecaps and the wind deflector on the truck isn't needed.
