Average fuel mileage on a 35' with the V10??

We have been looking around for a slightly used Class A with the V10. I have narrowed it down between the Tiffin Allegro 35QBA and the Georgetown 351DS. We also plan on towing a Jeep Wrangler behind it. Just wondering what kind of fuel mileage I can expect with this motor?? Any feedback will be very much appreciated!

  • About 8-9 with my 30'.
    Love the V-10!
    Winds definitely seem to make a big difference.
    I have a ScanGauge on the dash, so that gives me a good pic of whats going on.
    I like to use the power/coast method whether driving my MH, Jeep or Pick-up.
    Steady power to get up to speed quickly & then coast as much as possible. Anticipate stops and start coasting asap, trying to never use brakes.
    Seems to work pretty good for me.

  • About 7 for us, but we go around 72mph on the highways which is about the average speed of the rightmost lane. Seems to make a huge difference which way the wind is blowing. Air drag is the biggest killer of MPG on these motorhomes, and increases exponentially with speed. I've never been able to go 55mph on a long trip to check out how good it could have been.

    I disagree that the V10 is thirsty, seems that I have enough HP to climb hills as fast or faster than many diesel models, and it puts out as much hp, albeit at higher revs. So it's several MPG less than the smaller diesels, but the pump price and ease of keeping make that an even wash. So, dollar wise, it seems no more thirsty than the comparable diesels.

    Anybody got spec's on the specific fuel consumption of the V10 per hp vs any others? (at 2,000 rpm's, for instance) I'm thinking it's pretty similar, and about the usual 30% less efficient than diesels.

    much closer to 7
  • We average 7-8 mpg towing our Jeep. We drive 65 on highway. V10 is a great engine, but she's thirsty.
  • 34' V10 towing Jeep. I get that 10 mpg towing down hill with a tail wind. My honest average has been 6.9 mpg. I just fill up the tank and having fun until the money runs out.:B
  • About 8.5 with the RV in my sig. Driving 55 to 60. No toad. Very happy with the mileage i'm getting.
  • If you own a Wrangler you already understand poor MPG and bad aerodynamics like I do. :)

    We've had our 2007 Winnebago Sightseer 35J since 2007, I love it. My MPG can really vary since I live in an area with high winds. My low MPG towing our 4 ATVs and trailer would run about 6, highs were 10 if I had tail winds. Over the years my average towing/not towing, mountains/flat lands all combined is 7.9. Most of that was towing in the mountains. Now that the ATVs are gone and I don't tow with a full tank of water and an extra 40 gallons of fuel we're seeing average of 8.7 but I have yet to setup the Wrangler as a toad.
