Has anyone ever tried an air deflector to improve mileage while towing? There are several out there. Found this one with a quick search: http://www.amazon.com/gp/product/B00...dp_o_pC_nS_ttl
The manufacturer claims 3+ mpg increase...I've seen reviews that claim 1-2mpg increase. I'm sure there are a lot of factors (type of vehicle, trailer, etc...). Just wondering if anyone has any experience with them or feedback. Granted, it would take quite a while to recoup the cost with only 1-3mpg increase.
I have heard that if you use an air deflector, you should tie down the propane tank cover due to the vacuum that is created between the TV and the trailer.
