2003 40' American Eagle with Cummins 400HP.

62-66 MPH is normal for us and 8.5 to 8.8 on mostly flat land in the SE.

8.2 when towing the car on a trailer, or when going 70 +/-

MPG
 
What an interesting thread !


Loads of variables to consider here. i.e. terrain, weather, vehicle size, amount it's loaded with ( weight ), towing anything, traffic conditions, how fast you like to go, kind of power train,

maintenance history, etc., etc., etc...


Our HR 38WDS give us around 8.0 mpg if I keep the speed below 75 mph with cruise engaged....and that WITH the generator running ( which we always do in the warmer climates ) and WITHOUT the dash A/C running.


If I keep the speed a little lower (62 to 65 mph), it will get around 8.5 to 9 mpg.


Not to sound like a smart ass or anything, BUT if someone is going to invest in a large diesel pusher class A, I personally don't think they should be too concerned with whether their coach will get 7 mpg or 9 mpg.

Some do ask such as myself, but I do't let it stop me from getting what I want and enjoying it.

I don't own any thing that gets great MPG's but then again I won't buy something that gets GPM if I can find something else that gets better.:whistling:



I am impressed that I have seen truthful answers from a lot of people about their MPG's. On the pickup truck blogs the people just can't seem to get it right and tell the truth.

I will admit it's not as good on the gasser MH blogs either.



I thought the same thing the other day but didnít comment. The avgs seem reasonable. Iíve seen others before that seem inflated.

We just got back from a trip and I filled up for $2.14/gallon of diesel fuel. I checked the mileage and we averaged right at 10 mpg. We kept the speed right at 63/64 mph.

I have the same ISM engine, in the 450 HP version, same size coach, towing a F150 CC 4x4m and I get about the same MPG as you.

Anyway like you, glad to see honest answers instead of having to drain the tank ever so often

It isn't just the pickup drivers that can't tell the truth about fuel mileage, I camp at Eminence mo. at a horse camp, some times there's more than 2,500 vehicle camping there, up to 6,000 riders, naturally I haven't talked to all of them, but in the 15 years down there, I have talked to a lot campers there, and else where. there's a lot of different mileage between rigs, down there, but on here they all are about the same, between a 300hp or 500hp. I like when the guy says he gets the same mileage whether he's pulling 15,00 lbs. or driving empty. I think a lot these guys are using there computer put out, try pen to paper. my 02 f350 7.3 gets 25 miles to the gallon, computers shows. But when I take the pen & paper, gallons into mileage, it comes out 17 mile a gallon.

I do believe you Jeffrey
But Not some other posters above.
The last ten years I have averaged ( 6.2 ) mpg

I drive 62 to 65.
500 hp. Ism.
This includes running aqua hot and generator.
I am usually towing something
F150
4 door jeep
Or a car trailer.


In my opinion ? Most of these mpg conversations are
Only good for Bar talk Blowing smoke. Ha
Kentucky Bourban anyone [emoji16]

Statistically
A two to 5 year look at total miles and total gallon s purchased is a start to figuring accurate millage.

Then there is idle time ?

We Are talking a home on wheels.

I can't tell you how many times I have had to reset the MPG factor on my VMsp because it kept creeping up. It always felt good looking at it, but the manual calculation of miles driven divided by gallons used brought me back to reality. :sad:

The number of gals consumed (based on fillups) was within 4 percent.

That's amazing. Don't ever sell that coach. It's a gem of economy for a 40'er.

Country Coach Affinity CAT12 Diesel
 
I have a 40 foot Country Coach 450hp CAT C12 With Alison transmission. I get 8 mpg towing a Jeep JKU on all terrains. If I am traveling long straight roads out West with no incline I get 11mpg.

Use a computer readout attached like the ScanPort2 and you will see instsnt real-time results and discover the "sweetspot" speed where you get best mileage.
