MPG in your C or super C

1993 29' Cobra Passport E350 460 V8 average 9.1 mpg USG at 60 mph with nothing towed. GVW is 11,500 empty. At 65 mph she drops down to 8 mpg but at 55 she bumps up to 11.5. The best I've ever measured from a full tank usage was 18 mpg! This was achieved averaging 50 mph through slow acceleration and by driving uphill between 40 and 45 while coasting down hill up to 70.

7.32 MPG for 2559 miles this summer.

2006 Lazy Daze 27' on a E450 chassis with V10. Was exactly #14,050 on departure! towing aa 1994 Suzuki Sidekick guesstimated weight ~ #3000. Mostly flatland interstates at 60MPH.

A 29ft,montclair, by Monaco , not towing, still 12.6,towing still rite on ten. 60mph, 22k on the clock , now it's all happy-camping

We have 50k on an ’06 Jayco Seneca 34SS at 20,160lbs plus 3,740 when the PT Cruiser is behind on a car caddy. I see right on 8.5mpg towing or not as my travel speed is higher when not towing. Best ever for a tank was 9.8 and the worst was 6.5. On the last 28 day trip from SoCal to Reno and Portland and returning down 101 to the bay area and then I-5 I got 8.75mpg. The tank holds 80 gal. and I spend them frivolously.

2011 Lazy Daze 24' V10 E450. 9 MPG overall.

Once in a while on easy steady 60 MPH trip it will get 10 MPG.

Just returned from a 2341 mile trip to Oregon and back home in Idaho.
1998 Four Winds 22rk V10, weighed out at 11800 Lbs when we left. Speed limit in
Oregon is 55 mph on just about every road. We used 168 gallons of gas at
13 miles per gallon. I never saw a gas pump with 85 octane, 87 octane was the lowest. Prices in Idaho were $3.55 a gallon, in Oregon the range was $3.85 to $4.05. The Four Winds did just fine never gave a problem.

Explanation:

Please understand that in Oregon, even though the speed limit is 55 mph, there is hardly a straight interior road in the state. They are all two lane with passing lanes every few miles. When you drive highway 22 and 101 you can not stay at 55 mph, although the logging trucks and semi's are pushing you all the time. After five hours of driving highway 22, you'll think your arms are going to fall off. The only time I saw a semi doing 55, it was going up hill.

Why would I want to follow the speed limit? Oregon does not have a sales tax, they make there money off of fees for anything you can think of. Your first speeding ticket in Oregon for a minor infraction can be in the hundreds of dollars. With an out of state license plate, I stayed at 55 or less.

9.9 mpg at 72 mph pulling the jeep, w/ the generator running.

worst we've ever seen is 9.0 (heavy foot in the mountains)
best we've seen was 13.3 (60-65mph) mixed interstate & secondary roads atlanta to destin fl.

15 and change when not towing.
