Anyone using a 350/3500 class SRW gas engine truck for a camper hauler I would appreciate hearing about your mpg’s- make and powertrain spec - empty truck, camper on board, and camper & trailer- boat, enclosed, horses, or whatever Thanks

Can't use me...I'm DRW and old.....lol1990 F350 dually460 EFIZF-5 manual 4:10 limited-slipEmpty at 55-58 mph nets 12.5-14 mpg highway and 10 mpg around townWith the S&S TC @ 10,500lbs at 55-58 mph nets 9-10.5 mpg highway and 8 mpg around town.

2012 GMC 2500 6.0 Gasser 3:73 Gears, 2014 Wolf Creek 850 (Purchased July 2013), and a 16' Aluminum trailer with a SXSI have every gas receipt since the truck was delivered on April 13 2012. 90% of these miles are with the camper and trailer with SXS. I'll be calculating this past years (April 13 2018-2019) mileage after the trucks birthday.2017-20184,332 Miles Driven424.87 Gallons of gas10.19 MPG$1,219.25 Total gas expense$2.86 Avg per gallon2016-20173,786 Miles Driven378.81 Gallons of gas9.99 MPG$1,961.45 Total gas expense$2.53 Avg per gallon2015-20164,572 Miles Driven432.11 Gallons of gas10.58 MPG$1,133.19 Total gas expense$2.62 Avg per gallon2014-20154,500 Miles Driven421.42 Gallons of gas10.67 MPG$1,515.11 Total gas expense$3.59 Avg per gallon2013-2014 (camper Jul 2013)6,557 Miles Driven581.33 Gallons of gas11.28 MPG$2,222.86 Total gas expense$3.82 Avg per gallon2012-20137,058 Miles Driven537.22 Gallons of gas13.13 MPG$2,133.05 Total gas expense$3.97 Avg per gallon

2005 8.1L with a ~4K lb basement type camper. I’ve only checked the mileage a couple times, with a mix of freeway (65-70mph) and 2-lane highway.About 8.5 with camper only.About 8 with a 2k lb cargo trailer in tow.Again, limited sample and was doing nothing to maximize mileage. Vacation time is more valuable to me right now.

We have a 2016 Ram 2500HD, 2WD Crew Cab with the 6.4L Hemi. In 2017 we traveled from Georgia to British Columbia and Alberta and back stopping at Glacier and Yellowstone National Parks. We were carrying a fairly light Adventurer 80RB coming in around 2,400 lbs as loaded. Covered about 8,650 miles and averaged 13.8 mpg hand calculated. Over one stretch of 300 miles with a tail wind we achieved 20.2 mpg while the lowest daily average was 12.8. This was driving sedately between 55 and 65 most often with the occasional 70 mph for short periods of time.

I have a 2015 Ram 3500 6.4 gasser and with the Ascent 85 RE camper on we get 8.5-10.5 mpg. With it off 13-15 mpg.

Ok under acceleration in my Mustang, but not so good in a DRW climbing a mtn. ;). For that, I’ll take the smoothness of my F450 doing less than half of that number! I guess we drive what we want though.

She was the best truck I could find way back when, that I was willing to pay for, and I've never regretted it. Red is without a doubt the best truck I've EVER owned. Even over the newer CTD and PSD that I owned...she just does her job flawlessly, and is quit the hotrod empty.

68 divided by 16 = 4.25 mpg . That's a hefty price for sound affects lol .

That's what it took to get UP the canyon at any decent speed...it is what it is.

My currant '94 got 11.6 loaded and 13.6 empty at probably 1,000 pounds less than MK and BF Ford.I have not hit 10,000 pounds total weight with my TC and truck...I have been running 96-9750 loaded when I weighed..It is heavier now but under 10K..

Heck I got 9.5 mpg overall on the 1,100+ mile trip last year at just under 17,000 gross. At one point I went through 16 gallons of Oregon garbage fuel in 68 miles...climbing a 4-7 percent twisty canyon Highway in a 20mph+ headwind the whole way, in 3rd and 4th. Nothing like the scream of a 460 doin 5,500 rpm...sweet sound!

2019 GMC 3500 SRW 6.0 Gas Long Bed, 4Dr
Unloaded 12mph
Loaded with a 2400 lb camper and towing a 2500 lb trailer 9 mpg

The new truck is much quieter inside than an identical 2013 that I had.

Hope this helps

True enough , but the reference was for the very same truck over the years with significantly better mpg when new . I think Morsnow explained it . First year truck empty , then camper was added , then trailer was added .

Agreed! These new transmissions are wonderful, much smoother shift transitions with less aggressive jump between gears with a 6 speed vs an old 3 speed.

Morsnow , to what do you attribute the loss in mpg from 2012 to 2018 ?

No camper in 2012-2013. Other fluctuations are due to weight changes of my load. Most of our trips include running up and down Alaska's mountainous highways with a trailer loaded with a SXS, firewood, 20 gallons of extra gas cans, and a ice/beer cooler. The campers weight is pretty steady, always a full water tank and food/clothing. We are at a much lower elevation than the Rockies which helps with a gasser's power.

Aerodynamic power requirements definitely affects mpg.

I spoke to a man driving a 15 or 16 F350 6.2 gas 4x4 with a Cirrus 820. He sees 11 to 12 at 65 mph in calm wind at 6-8000 ft, as low as 7.5-8 bucking a Big Headwind.
