class c with v10
I'm looking at a class C on a ford chassis with a V10 engine and no big cab over the front. What kind of mileage can i expect on regular country roads while staying at the speed limit.

It's over-all length is 23'-8" and is considered very aerodynamic by motorhome standards. Good aerodynamics helps both with fuel economy and vehicle control.
Sorry about that. It’s a 2006 Ford E450. 25 feet long.
I advise not to exceed 65 mph on interstates, but 5 mph less at 60 mph is ideal for fuel economy and vehicle control. At 60mph under flat, no-wind conditions, our ScanGauge-II monitor, we see 11.5mph while towing our 2006 Jeep Liberty 4x4, but realistically our trip average of 4000 to 5000 miles of driving, we calculate 9.25mpg. We average 10.5 mpg not towing anything.
A 2006 E450 compared to a 2006 E350 for the same "SHORT" model motorhome, will get roughly ONE MILE PER GALLON LESS because the axle ratio inside the rear differential is geared for a heavier motorhome. The E350 engine rpm will be lower applying less throttle. But as the rig gets heavier, the numbers drift to favor the E450 chassis for the application, including fuel economy. The breaking point between the two is "fluid" due to so many variables including length, aerodynamics, weight, and towing. Also, the E450 frame is a little thicker than the E350, a structural consideration when stretching the wheel base.
Our 2007 Phoenix Cruiser MANY PICTURES HERE is on a 2007 E350 chassis. It has an unmodified, standard 158" wheel base.
