For those of you with the Ford V8, 7.3, what kind of mileage are you getting. I’ve read everywhere between 6-12mpg. Specifically, I’m looking at the 27’ 2441 or 2440 model. Thanks.
 
I'm assuming that you are asking about a motorhome chassis.
Therefore I am moving your thread from the General Community Discussion section to the General Motorhome Discussion section since your questions are specific to that particular sub-forum and are not general community questions.
 
Behave yourself with smooth acceleration, and look well ahead of you to make braking smooth…..and you should get between 8-10 MPG.
Your floor plan is very similar to our 25’ rig, except they extended your rig to put the bathroom across the back of yours.
 
8-10 MPG sounds about right. There are a lot of things that will affect your MPG. How hard you accelerate has already been mentioned. Throw in a good headwind, and your MPG will be in the 6-8 range. It depends on how strong the wind is and how fast you are trying to drive into it. Switch that to a tail wind, and you could go up to 12 mpg. Every tank will be a little different.
 
I have a 31L5 and with full fresh water n most of the time full fuel driving 55mph-60mph I avg 9.8

I have a 25’ Forester LE with the v8 7.3. I have driven it for 3 yrs. It has 28,000 miles. I try to always drive at 65 mph. I get between 9 and 12 miles per gallon depending on the terrain. It’s a 2351 model. Weighs Approximately 12,000 pounds.
 
Our '24 GT5, which is larger than what you have will get 8-10 mpg at 60-65mph and towing an 05 escape on a dolly 7.5 to 8.5mpg experienced on our run from Chicago to Orlando last December. We've got 11,000 miles on her now and the overall average mpg on the dash shows 7.9, it was 8.2 prior to our Wisconsin trip below.

As mentioned above, head winds are a killer. A trip into Wisconsin last October pulling the Escape was in the low 6's with 20-30mph head winds.
 
Once you get the beast rolling air resistance becomes the major fuel consideration and being exponential air resistance is twice at 70 what it was at 50. Slow down! Doesn't mean you burn twice the fuel at 70 than at 50 but you do burn more.

I'm pulling a brick of a trailer. When I drove 300 miles across the PA turnpike several times a year to Gettysburg I needed a fuel stop if I drove at about 70 but could do it quicker and with no fuel stop if I drove right around below 60. Your mileage will be in accordance with your driving habits. Higher speed doesn't always get you there quicker when you have to stop enroute for fuel.

Our F53 Chassis under the '21 Pursuit gets ~8 while pulling the CMax Toad and ~9 without after 20k miles of record keeping. The dashboard says it's 8.5/9.5 partly due to our rare genset usage and partly due to gauge error.

Note 1: Headwinds cost about .1 mpg per knot.
Note 2: Coming down off of Emigrant Pass I got 34 mpg!
 
I have a 2023 Georgetown GT7 36D7 - 38 ft - I get 7.8 mpg and it has stayed that way solo or towing my car with a dolly.
 
I have a 2441. Windy or not, with empty or full fresh water tank, 55mph- 70mph = 8mpg according to dash computer.
Both of my Ford dash computers consistently overstate my mileage by ~10%. I always those numbers 'guesstimates', and calculate the actual fuel economy when I fill up. When I tow, if it says 9.6 mpg the actual will be 8.8 to 9.0.

I have a Ford F-250 Super Duty with a 7.3 L 460 engine. We pull a 2019 Rockwood Ultra Lite 2612WS 30'. We have been full time going on 5 years. Gas mileage is relative to terrain, wind, etc. , but I get a quarter tank of gas per hour, or 8.5 - 10 mpg. Don't worry about the gas, enjoy where the gas takes you!
 
put solar on top
save $$$ campground fees for overnight stops
enjoy the trip

THEN.... fergetaboutgas milage... you going to average 10mpg it will get worse more than it gets better

mpg tips:
always read the traffic and try not to STOP start slowing down way before getting to a traffic light

after the inevitable stop... don't smash the accelerator pedal and try keeping up with traffic
they are already mad at you for being in their way in the first place.....taking off faster, won't make them any happier.
 
I have found that regardless of the engine, the truck, whether its towed or not, they all get the same MPG, 8-10. You just can't defeat wind resistance. Diesel, gas, when under a load with resistance, 8-10 MPG.

Just wondering. Why people answer questions when they have a completely different rv with a V10 not a V8 when the question asked was specific.
 
I can’t comment on your mileage because I don’t see anywhere you’ve posted what type of RV you have.
That said, although we have the Ford V-10 in our present Class C, and I’ve had a Ford V-10 for 10 years in our previous Class A, we vacation with several friends with motorhomes with several versions of the Ford V-10 and V-8. In like travels, we have compared gas consumption
(fuel mileage) even when travelling together on the same roads, and same speeds. When all was said and done, the differences would barely pay the difference between variously equipped campgrounds we stayed at on during our trip.

This is my basis for posting the answer I offered, and after reading everyone’s answer since I posted in post #3, it appears that many agree.

Thor Magnitude GA22,
10.2-10.4 with or without Jeep Grand Cherokee Trail hawk in tow. 7,000 miles x country Dunstable, MA to Zion np and back, 2024.

However on a x country trip out to Denver in 2022 I experienced 9.4 from the Mississippi throughout the Dakota's down to Denver and back. The winds were very strong and I was not towing anything.

My sense is that the engine and the e-350 vehicle is designed to operate in the ~10-11 mpg range regardless of conditions.

Marvelous system. Accelerated well, stops well, easy to maintain, a pleasure to drive.
Wonderful machine.
Enjoy her.
