1993 32ft Itasca Suncruiser class A.  Gas 454.  I can get 7.5mpg as unladen as I can make it (empty black/grey tanks and 20ish gallons in the fresh tank).  If I load it up with water, hook up the trailer with the car, and run the generator the whole time I get about 7mpg.  If I slow it down and keep it at 50-55 mph, I can eek another .25mpg out of it, plus or minus.

Basically, I just try not to think about it too much.  I only do the math at each fuel stop as an early-warning system for mechanical issues.

Yes, five motorhomes (C & A, gas & diesel) over the years and 7-8 mpg is about right.  Many things affect it - terrain, speed, Aqua Hot, generator running roof air conditioning, altitude, and most of all your foot.  Current diesel pusher at 114,000 miles engine computer says our average is about 7.6 mpg.

if you have to worry about fuel mileage you need to find a different hobby because they all are horrible or just grin and bear it like the rest of us.

A Prius gets 50 MPG and weigh about 2500 pounds.  So it gets a score of 125,000.

My motorhome gets an average of 7 and weighs 25000.  A score of 175,000.  Thus it's more efficient on a pound per pound basis.

2001 Winnebago Realta - 22 mpg while going up and over the Rockies.  Try topping that.  Not even my stick shift VW camper from 1971 did any better than that.

A tiny little Rialta (spelling is correct) is not a "motor home" in the context of this thread. It's a van with a little 2.8 liter V6 engine.

And I don't believe your claim of 22 mpg in the mountains, either.

Agreed.  Perhaps completely unloaded on flat ground doing 50-60 mph might get you 20 at most.  My f150's 2.7 v6 ecoboost gets 22 mpg through the rockies completely unloaded...  ::)
