gas mileage with a v10

With our 2003 Itasca 30 footer towing a 2700 lb car we get 7 to 11. I know that's a big range but it really depends a lot on wind and terrain. I would say a long term average would be 8 to 9.

I get between 9 and 9.5 on average.

FORD V-10 mailage will be approximate depending on the speed.

At 55 Miles per hour speed.

Between 7 to 9 miles per gallon flat land small hills, more miles if going with the wind less if going against it.

Mountain driving is not possible due to the amount of terrain variation.

City driving is approx 4 to 6 miles per gallon less in stop and go.

Most of this is from my 2001 E-350 FORD V-10 24 foot motor home pulling a Suzuky Grand Vitara 2001 4 X 4 standard shift.

Chevrolet based RV's have diferent engines and rear end configuration and will have diferent milage.

27' running around 11K lbs - here's the numbers from our trip last summer:


and another trip late last summer:


Cheers!

I've had my 32 1/2' Itasca for about 16 months. During that time I've been averaging between 8 - 8.5mpg, not using cruise control, or the dash air, while running the generator on most trips, usually running 60-65MPH. Driving in flat southern/central Florida, where the highest elevation is a highway overpass.
This past weekend I drove down to Key Largo and made a conscious effort to stay below 60mph. I averaged exactly 9 MPG. On the way home, driving the same speed, with the tow/haul mode on (for the first time ever), I averaged 9.7MPG. (it had been 9.8 right before I took the picture).

we have a 2012 winnebago aspect 28T. We tow a 2013 Hyundai Elantra (2700 lbs +-). We just returned froma 4500 mile trip with the rig, our 1st with it. I installed a 5 star tuner prior to the trip and it must work. We drove 62 mph 2300 rpm got around 8.5 mpg, went to 65 mph 2500 rpm got 8 mpg overall. Drove across Iowa to Neb at 65 for 9.3 (hand calc'd). Drove to colorado at 70 mph got 8.3 (hand calc'd). Using the scan gauge as illustrated above had highs at 10 low at 7. All due to terrain and winds. We drive with cruise control on and dash AC. So from what others are saying about no dash ac and slow speed there is not an apparent need to drive slow from what I can see! At 8000+ in colorado SG indicated 10+ This was on the high plain from alamosa to over to the base of Wolf Creek.

As the engine broke in the performance and milage got better. Without the tuner when we 1st bought the rig, trip from prescott az to Lakeside to Tucson best we got was 8 mpg period. Yes some good pulls were encountered. salt river being 1 another is from I17 to payson to showlow.

The wife does not like to dawdle thus the higher speeds. Same deal with my F350 diesel with and without the TT. At 80 with the diesel I get as good as I get trying to go 65-70 and with the trailer at 65 its about the same as 60. Not enough difference to justify the slower speed.

So it will all depend on how you want to drive and how you actually drive the rig it would seem. Got a friend who has a DP drives at 55 claims he get 13 mpg! says he drops to 11 at 65? So again everything is variable. If you ead up on how to economize using CC is recommended as it will maintain the settings better than the right foot will, variations on hills but overall the CC is recommended. I also do not use tow/haul on the rv or pickup except for starts stops on hills and use direct for long pulls and descents.

These are my observations and you need to take them as that and nothing else. I do think tuners help overall but the cost is not something you can plan to recover due to any mileage savings and I do not buy them with that as a primary goal. Both my PU and the RV have rv related tuners installed and we are happy with the results they give.

I just got back from a coast to coast trip along I-40 and I think I averaged around 7. The speed limit was 75 and there were a lot of mountains... So.... I could have done better, but I tend to have a lead foot. Maybe I could have gotten 8mpg *shrug*

I was driving my Winnie Minnie 31c with Triton V10.

2012 Freedom elite 31R, 60,000 miles. Ran with dash air on, mostly flat highways, no tow/haul mode, never went over 60 mph. Trip to Daytona beach, hand calculated 9.9 mpg.

My Class C (26' single slide) towing a Chevy Cobalt went 7733 Miles last winter, used 1034.43 US Gallons, ($3475.71 at a calculated Average of $3.36 a gallon) I can then further determine that I get 7.48 MPG Avg.
