Huge help, KB!! I've had a hard time with deflectors as the RV world is one in which the desire for better mpg is a constant question. The lack of good record keeping is one hindrance, the annual miles another (for comparison purposes). And more are the differences between rigs (TV & TT).
So about a 4.6% mpg increase on this trip.
Which is in the neighborhood of a 9% drag reduction (wind averaged).
Am looking forward to more as it is available.
