waxing to increase mpg
I would like some feedback and perhaps personal experiences in how a good wax job on the front or your TT improved your mpg. I know that waxing is important for proper care of the TT skin and that air...

Waxing the front will not increase MPG. Changing the profile will. I bought an old school wind deflector for my 11.5ft tall TT to put on the top of my Excursion. I was getting consistent upper 6 for mileage. With the addition of the deflector I gained approx. 1.2 mpg!!! For these to work properly they have to be as close to the trailer as possible and have the correct angle. They will not work on a pick up if put in the cab with a TT, maybe a fight wheel.
I've had it for a couple years now and it works very well. You can feel that the engine works less due to the decrease in wind resistance, and the bugs are 90% gone on the front of the trailer which shows how the wing works to push the air up over the trailer. I have a small 6" line of bugs on the very top edge of the trailer. Just for the heck of it on one trip I didn't use it and my mileage went back to the 6.8 range. So yes real world results are that they can work if sized and used properly.
