If I install Air Tabs & Solid Aero Hubcaps will I get 10 mpg

A belly pan will do the most to reduce drag compared to tabs and hubcaps. One rule of thumb is that 50 % of aerodynamic drag comes from the underneath of the vehicle.

Another rule of thumb is that aerodynamic drag increases with the square of the speed, so your best and easiest way to improve mileage is to slow down.

Wow strange I was thinking belly pans, even a air scoop/damper in front to help with the wind going under motorhome, maybe that's where I need to do work, my 10 mpg is ridiculous but it sounds good, I average now 7 mpg no wind no hills pulling my Jeep behind.

I like my current motorhome 2008 Bounder 32W but would have been nice that Fleetwood would have made it a little more aerodynamic than it is, cant see why they are not doing this today with most motorhomes, always so boxy looking.
