Which RV have the best aerodynamics? A, B or C?
Hello, I'm planning to buy a new RV next year and I'm a newbie. For the same height, wide, weight and lenght, which ones have the best aerodynamics? A, B or C? Thanks,

So a 4000 pound car with 250 HP gets 30 MPG compared to a 30K pound motorhome with 250 hp that gets 8 MPG because of frontal area?
Once you get that heavy load up and moving, yes it's mainly the frontal area.
I keep detailed notes on fuel economy.
Here is one of my notes:
Hauled 4 tons of fertilizer (+ 2500lb spreader) = 10,500 lbs.
Drove 55mph got 12.8 mpg.
Returned empty 2500 lb spreader at 55mph. Got 14.5mpg
This was with my '13 Ford Powerstroke.
I do the same thing when hauling cattle. If I take 5000 lbs of livestock to the sale barn and then return empty, the mpg difference is about the same as above.
