What's your mileage?

That sounds pretty typical. I haven't had a C for several years, but I had a 1998 Gulfstream built on an E-Super Duty (which later became the E450) with the gas V10. I often towed a 3000 lb-ish car. My mileage ranged from about 7-7.5 pulling the car at freeway speeds traveling from Western to Eastern Washington, and I could squeeze out close to 10 running solo down to the ocean with slower speeds and less freeway driving.

That works out to 22.6 litres per 100 k or 10.4 mpg US (13 mpg imperial)

Mine was a 37' Class A 8.1L vortec allison. With towed
Original towed a 4.000 pound Chevy Lumina APV I got about 8 MPG
Second towed 2500 pound Dodge Neon about 7 (I do know why)
Now tow and a fresh wax job I hit 11 going East 10 west.

Yes I waxed before my semi-annual migrations.

Now days the MH is gone all I have is a 2014 JEEP with a ceramic wax job and a half (Actually two complete coats of heavy duty Ceramic coating

Around 23 MPG average... 30+ at 65mph 40 at 55

I looked up a 2020 Jeep Electric 22-23 MPGe So I'm as Green as if I drove an EV. perhaps Greener..

I have nothing to compare that too, cause I’d go to sleep if I drove 50mph unless it was in a 45 mph zone. I typically do around 65, and usually get in the high 7’s.

I'm a slow driver at 80 kph (50 mph)

In this part of Cannuckistan everyone, including the nun driving the school bus, would be flipping you off for doing just 80 ……. In 60 zones! LOL

Seriously, at 80 in an 80 zone, you will attract a lot of attention and very likely get pulled over to see if everything is OK, in a 100 zone you’d likely get a ticket.

I do however put a lot of miles (km’s?) on my C doing 90 - 95 (in 80 zone) and generally get 11 - 11.5 Imperial (9 - 9.5 US) mpg doing so without a trailer, 9 - 9.5 (7.5 - 8 US mpg) with a (2k pound) trailer.

Before our current 42' 5th wheel, we had a 27' Class C, E-450, V-10. Drove at the speed limit or 60 MPH when the speed limit was 60 or higher, did not tow anything. 9.91 MPG overall for the time we owned it.

Can't say anything about an 80kph speed, but I tend to do 95kph and I am in the mountains and Alberta so pretty mixed driving.... get the hills in the mountians and the prairie winds in Alberta.

if I stay driving nice (95kph) I can get as low as 18L/100km (13MPG US/ 15.6MPG CDN) when I am in a strong headwind and try to do the speed limit in Alberta, that can drop down to 22L/100km (10.6MPG US / 12.8MPG CDN.

I did just tune my truck a bot better so I will see at the end of June what I get going to Alberta and back now. It sure improved my empty fuel milage.

8 miles to a gallon E450 V10, beautiful powerful engine.

Chevy C3500 with mildly built 454 gas, and 5 speed manual pulling 35' 5th wheel with 3 slides. I average 4 MPG. Needless to say we dont travel very far from home.

I've got two 30' Class Cs with the 450 Superduty V10. I tend to drive the speed limit (so 65-70mph on most freeways around here). I always seem to get between 7.0-8.0mpg (average around 7.5mpg). I have a smaller 23' Class C that seems to get a similar mpg (...thought it would be better, but sadly no).

I've owned 2 diesel pushers that had instantaneous fuel consumption readings. and that fuel MPG really suffered above 60 MPH.
