The owners of new Ford V10 powered small motorhomes about the size of ours would also "kill" for the 8-10 we get. According to FMCA articles they are getting around 6-7 with multi-speed transmissions, port FI, etc.

Compared to most SOB, esp those of ~40 yrs ago, the GMC is light years ahead of other makes in terms of aerodynamics. The stated CD of .031 is not at
all bad, howver the other factor is frotal area...which is rather large.
Lots of other class A owners would have killed for the 8-10 mpg we get, especially the old mopars.

Another factor is that drag goes up as a funtion of speed. In a NASCAR racer hitting 200mph, its a huge factor. If you are cruising at 50-60, I think
you would be hard pressed to see any measurable milage gain.
But a good running GMC CAN bury the speedometer, as I found out when I was young and foolish.
