2000 winnebago ultimate advantage Cat 3126 300 Hp Allison trans. I am averaging between 7-9 at 65 MPH. I am new and have not hooked up a trailer yet. I have a 2013 Ford Cmax that I want to tow 4 down, but have yet to spend the money to get it ready.

Or stand at flying J and watch a DP owner pump 150 to 200 gallon in.

Its a mindset.

Different strokes for different folks.

People that are ( serious ) contenders for any of these
lifestyle s never ask those mpg questions.
Life's Priorities


NOT True.
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.

34 ft DP Cummins ISB 370 60-65 MPH. 8 - 8.5 MPG

34 ft Boat Yanmar 370 HP 8 - 9 MPH. 2 - 2.5 MPG

Don't worry about it... if you enjoy it just refill before empty and keep enjoying it. Fuel is actually a fairly small % of overall cost.

Got a good laugh out of this one, that is a written fact about the Pickup Drivers not able to tell the truth about the mileage. Before I offend all of them maybe 10% do answer truthfully

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

We get about 9 MPG and try to run about 65 MPH on the highways. We have the 450 HP Cummins.

How do you know these are truthful answers? There is really no way to verify.

The forum's accuracy in other areas, such as how to repair this, or reset that, or whatever, is maybe 50% guesswork.

Our older, lighter coach, 30,000 lbs, 6CTA Cummins 325HP, 8-9MPG hand checked. Running around 62MPH.

Back in the day, 8V71T, 80,000 lbs, 60+ mph, 4.2 MPG over 400,000 miles.

This is the truth, just hook me up to the polygraph!

Good come back, at least you aren't one of those draining the tank like on the pickup forums

As you know many of the numbers over there are a bit wishful, those posted here are in line with what I have personally seen so I believe them, had several diesel pickups so I know whey the others are shall we say blowing smoke

Interesting related note from the Cumins engine class at the Tampa RV show. Reducing speed from 70 to 60 will add 1 mile to your miles per gallon!

Sorry, but I have to question your mpg. I also have a 450 Cummins in a 43' coach. At times, I can get 8 mpg if I'm not towing anything with no wind and on flat ground running 62 mph. Those conditions rarely happen. 7.5 is a realistic number in light and variable wind without a toad. If I rely on the dash computer, I get over nine, but hand calculation tells the truth. I wonder why you can get 20% better economy driving a little faster than I do?? What's the difference??

34' Winnebago Journey 6.7l Cummins 340 hp 10-11 mpg cruising interstates at 62 mph. But I hate interstates and get 9-10 mpg on the back roads (US Hwys) with stop and go and max speed of 55 mph.

We have been tracking milage and fuel as we are very new to this. Worse was 8.9 and best was 9.4. I'm usually pretty good with numbers.

2000 Country Coach. 330 ISC, 8 MPG

CWSWine 01-20-2019 04:42 PM

2017 Discovery LXE 40D with 380 HP 1150 Torque. Driving 60 mph with no headwind towing a Jeep Wrangler at about 38,400 combine weight we get close to 8 MPG. Overall towing, we get between 7.2 and 7.6 MPG.

I own a 2005 Travel Supreme Select, 500HP Cummins and tow a 2016 GMC 4 door 4X4 pickup at 65 to 68 MPH average 6.5 MPG. Then you need to figure fuel for the generator on hot summer days to run the AC. And Fuel for the hydro hot for domestic hot water and the furnace in cold weather.
