What is the fuel economy, or UNeconomy, on a "C".

flew from New Hampshire to Mobile Alabama to buy the unit, drove it
1900 miles home over four wonderful days, lots of fun, 9mpg @65mph
2006 E350 V10 21ft 10klbs

My C is described in the sig. I get 9-10 mpg.

2007 E350 with gasoline 6.8L-V10

- trip average over 4000 miles
- all kinds of driving conditions
- rig weighs 9200 pounds empty
- aerodynamic shape
- always towing the 4300 pound Jeep Libery pictured
- normal cruising speed is 5mph over posted speed limits for towing

Trip Average 9.2mpg

A shorter trip without towing averaged 10.2mpg

Mpg varies a lot with terrain,(mountain grades vs flatlands), headwinds, and altitude as well as speed vs aerodynamic drag and rolling resistance. We get 7-9mpg with our 27 foot rig. I think that claims of 11 mpg may be based on inaccurate calculation. A class C motorhome is an un-streamlined box truck full of appliances, supplies, water, gasoline and occupants. If you can't afford fuel and all of the other costs of ownership and maintenance, motorhoming is not for you.

New 28ft V10 and we get between 8 and 9 mpg depending on wind. We weigh in at 12000lbs. We have a toad but haven't towed the toad yet. We keep it 62 mph.

Being that you are in Northern California you have mountains to contend with much like here in Washington State 8 to 10 would be good. I have a 26' Class C with the 8.1 Vortec running about 11,500 weight. I get 8.8 to 9.5 depending on where I go and how fast I drive. I would think that if you get 8 to 10 you should be happy. I plan on 9 and the difference between 8 and 9 on the 5200 mile trip we have planned this summer is about 57 gallons of gas or just 1 tank. I can live with that.

:S Rough rule of thumb if you have a 30 gallon tank you can pass 30 gas stations before refuling if you have 40 gsllon you can pass 40 and if you have a 50 gallon you can make it to the 50th station.

Put a good scan Gage to it Mine says 7.5 Not fuzzy math that way. You never know exact a mount of gas in take at fill up every time. And again if you worry about MPG this type of camping is not for you. Just fill it and enjoy it forget about this nonsense.

The winner, best answer posted this week.

3000 miles round trip from Maine to Orlando averaged 7.7 MPG-- Cruise control at 62MPH south of Virginia.
Got 12 MPG running with the trucks on NJ Turnpike at 2AM
