Any gain in MPG??? Wouldn't take many miles to pay for itself.
I honestly can't say, The first trip with truck and camper combination resulted in unbearable wind noise. I had to do something to reduce the noise. The deflector solved the noise issue and I have not been willing to go on a trip without the deflector in place. I have found on several 2 to 3 month 10000+ mile trips, that it requires close to 10000 miles to properly track mpg increases and decreases with a TC. For example, 4 years ago I took a 13000 mile trip from BC Canada to Washington DC, then on up to New Brunswick Can. and back home. On the trip eastward I was pushed by strong tail winds and averaged over 16.5 mpg on the first 3500 miles. However by the end of the trip average mpg was down to the normal 15mpg. A 10000 mile trip to Florida last year started with strong mpg numbers but by the end of the trip resulted with again 15mpg.
I have kept track of fuel economy for the last 50000 miles, the average mpg over that distance with camper on truck at typical 58 to 60 mph speeds has been 14.9 mpg.
