I'm looking for better fuel economy but it seems I do fairly decent with my truck....
01 F350 Dually with Reading Utility Bed loaded to the max with tools etc pulling a 73 29ft Ambassador also loaded down with everything I own... consistently gets 12 mpg at 65 mph

Just got back to washington from Indiana on a round trip vacation to Chain o'Lakes. We only got about 7 to 8 mpg with my '95 3/4 ton suburban, with the 454. kept the speed around 65 MPH, accept when we just couldn't keep up that speed. 40MPH over all those mountains is very slow, but we made it. But i guess 7-8 isn't so bad when you only get 10 in town and maybe 12 on the highway.

Updating from earlier posts, on our recent 4,200 mile round trip from Ontario to Florida and back, by way of New Orleans, we averaged about 12 mpg (US) with the Sienna. Sure, it's pretty flat (except north of Knoxville) but keeping at around 60-65 mph, I was happy with that.

2005 Toyota Tacoma, 4 litre 6 cyl, 6spd manual transmission. 20 mpg/ not towing
25/mpg/highway/ not towing.....15mpg towing 65mph and under....

[ROBERT CROSS]

Western NY-Simi Valley

11.4 average towing.

With all the comforts of home and room to spare.

FWIW... If PCM is calibrated correctly your DIC will match the GPS.

i second the "comforts of home and room to spare" usually after a week of "camping" in a stationary spot, me and the wife are ready for home. this time around (with our new to us airstream) 2 weeks of the nomad lifestyle doesn't seem like enough time!

gallon of gas $3.75
night at rv park $35
sleeping in my own bed everynight... priceless.

2005 Honda odyssey completely loaded interior towing our 1956 bubble through the willamette valley over santiam pass to smith rocks. 17 mpg.

What year is your Yukon Hybrid? Thionking about buying one to pull a 25' AS.

[BAB BMRZ]

cotons:

We've been towing our 08, 28' International with our 08 Yukon Hybrid for two and a half years now. Over 28000 miles. Most of these miles have been on trips in the West (one to the East to watch a Shuttle Launch), including more than 3 dozen trips over the Continental Divide and one over the Bear Tooth Hwy At 11K feet. We're sending this while on our way home from the Albuquerque Balloon Fiesta, 13.1 mpg, on this trip.

We've been been averaging (towing) 13-13.5 mpg over this time. Our best leg was from San Diego, CA (where we live), to Hamilton, MT, 14.9 mpg, our worst was Bismarck, ND to Pierre, SD 200 miles into a 50 mph head wind, got 8.9 mpg. When not towing we get 22 hwy 21 city. DW (lead foot) gets 19-20 city.

We try and tow light, the last time on the scales the AS weighed 6200 lbs loaded for the road. We tend to drive at 55 to 60 mph (1500 rpm or less).

2010 28' Flying Cloud; 2011 F250 Crew Cab, 6.7, gross combined weight varies a little but stays around 17,800 - 18,200 depending on which welder/genset and tools, rack, etc. Total 34,745 miles of AS towing to date (all trips from Slidell, La thru TX, NM, CO, WY, MT all seasons since May 2010 when truck put into service). Tow easily at hwy speeds 65-70+ mph. Avg 15.2 mpg towing. Total truck mileage is 37,370. Non-tow/empty 21.8 mpg. Noticed both towing and non-towing mpg increased about 8-10% when truck passed about 28k miles so current "instant" mpg is a little over the above numbers, ie, last tow back from MT was 15.9 but that is included in the 15.2 data.

What axle ratio does your F250 have?

Dennis

[dayner]

Dennis, the axle is the 3.31 E-locker. It's a 2wd not a 4x4.

Rats . . an accurately formatted response from a Ford guy. Those numbers look as good as those of us with pre-2005 Dodge & Duramax trucks where combined weight is usually less, but trailers sometimes larger/heavier. Think you can meet or beat the rest of us by slowing down to 60 and 16+ mpg?

Got any pics of the combination? Sounds like a work truck with a severe aero penalty.

A gasser work truck and a SWB would be easily mean a 50% fuel penalty by comparison. At $3.75/gl over 35k miles that is quite a few thousands of dollars towards the good.

Congratulations!!

So are you quoting your recent "instant" mpg or overall mpg or average mpg or ????? Confused what instant mpg means.

Instant MPG is the reading you get from a "driver's info center" or trip computer that's just based on your speed and current rate of fuel burn.... that's why it'll say crazy things like 99.99 mpg when you're going downhill off the throttle. It doesn't really mean anything beyond giving you a clue of how much your current driving condition is affecting your fuel consumption.

Returning from the bison roundup last week, we filled up south of Rapid City and made it to Blue Mounds SP in Luvern Minn. 390 miles with 20.5 gallons of regular fuel, nearly 20 mpg! This was all downhill, with the wind. Another tank got us home. The trip to Custer SP, uphill and into a really gusty wind we got about 13 mpg.

Well... We are now 2,000+ miles into our trip and are averaging 10.0 MPG with the 2010 Tundra CrewMax 5.7L 4x4 when we arrived at the Jackson Rancheria rally. I know we would be getting better MPG if my foot wasn't so heavy (it's hard to drive 55).

[TouringDan]

One advantage of the "instant" gas mileage readout is you see the reduction in fuel economy when you downshift.

You have got to drive gently to get good fuel economy with the 5.7L Tundra. I have a light load (4,300 lbs) and 2wd. I usually get 13-14 mpg towing and I drive at 60-65 mph. I just returned from an 800 mile trip solo- I really babied it to get to my destination (200 miles all flat terain). I got an honest 22.0 mpg. Then 400 miles of urban driving and the 200 mile return trip home, I got an overall trip average of 18.9 mpg. EPA highway rating is 18 mpg. I have no complaints (except the electonic LSD sucks).
