Post your MPG in Diesels.

[countrycampers3]

Hi everyone,
Looking at getting a diesel truck. Would appreciate your feedback on what you have, and what you get.
Please give me a Truck year, make, model, transmission, rear end ratio.

Empty MPG, City/Hwy.
Loaded MPG City/Hwy.

Plus were your at, Mountains, flatland, rolling hills.

Thanks Doug:C

Well thanks for all the info everyone. I see this post is not dead and it keeps on giving.
Update. I ended up getting a 2008 Ford F-350 dually Flatbed. And a New 2013 NorthStar Arrow 8.5 Love them both expecially the extra storage compartments on the outside of the camper.
Now these numbers are winter diesel and that tends to be a little less economy I would assume.
Empty 55mph - 15-19
Empty interstate 75mph - 12
T/C loaded - 9.5 any speed
Heres a photo.

7.3 6sp 3.73 4x4 125k

unloaded I get up to 18 but I don't drive slow enough to see the higher #s.
loaded in heavy winds and/or with a heavy foot we have gotten as bad as 10 but usualy around 14.

10.6 mpg after 3300 round trip from Redding, CA to just south of Loreto, BCS Mexico. The truck does fine with non ULSD fuel, 2nd trip.

Kayaks, bikes, 6 cases of american beer!!

05 duramax, 5.13 gears, 4x4, weighing about 19000 pounds with the aerodynamics of a brick wall, travaling typically at 70 mpg and I get 7-8. It can vary a lot of course. If I drove mellow and at 60-62 I can get over 10. Maybe when I am retired and don't have to maximize vacation I can slow down. Pretty good pounds per mile/gallon though :). My Corolla got 30 but weighed about 1/6th what my TC combo weighs so the big rig is more efficient at doing work for each gallon.

meatwagon,

Should get approx 15 MPG at 65 MPH and 16.5 MPG at 55-58 MPH with your 825 when traveling. How do we know? Our 2004.5 Chev D/A CC LB 4X4 with our option loaded Lance 915 (9.5' with the steel rear porch for my disabled wife) averaged 14.2 - 15.3 ate 58-60 MPH (cruise control) for the 44,300 miles we had it on the D/A truck. Was replaced in 2009 with our 11'4" heavy option loaded Lance that weighs 3872 lbs when shipped from California (weight as shipped is on the final inspection page in the owners packet) and has 38,700 miles and change carrying it with getting 13.7 to 14.9 MPG on the truck. Always has the porch on the back as it's a must. Wife keeps very accurate log books and it's all hand calculated but the DIC is also very accurate on the GM trucks. Our truck now has a little over 136,000 on it before we head to Florida with the 5th wheel behind on our annual trip from Michigan to visit relatives. Truck is and has been ONLY used for RV travel with the TC's or the 5th wheel since the truck was new but we've also added a 26' long 7100 lb TT last spring. Yes, we do a lot of rv'ing every year. Average 85 to 130 nights yearly and several trips across the USA and Canada and Alaska trips also. We are "travelnutz"

I think you're going to be very happy with your MPG's, we sure are and that's why we keep our totally trouble free truck! It's barely broken it now! Fantastic truck!

that would be nice to see.taking it on my first camping trip next . thanks for sharing.

06 2500hd lbz (all stock 3.73), empty city 15mpg, highway 19.8 avg. on 3800 mile trip from phoenix,az. to rock island, ill. and back (cruise set at 68) both ways. pulling my former toyhauler from phx. to flagstaff (1000ft. elevation to 7200ft.) at 65mph. got 9.8mpg. and it pulled the mountain grades like a dream. can't wait to see how it does with the lance 825 that i just traded the toy hauler in for.

The 14.3 mpg above includes many long trips in the fast lane..

Dodge and GM owners must be smarter...;)

Interesting how much the trucks have improved over the years. Compared to the 1996 Silverado my 2011 2500HD Duramax gets the same mileage empty and much better mileage loaded and in the mountains, while providing 765 ft lb of torque and 367 horsepower.

On a recent 3900 mile trip from Monterey to Montana and traveling through Wyoming, Utah, and Nevada with a 3700 lb. load weight the MPG average was 13.5 and that included a lot of miles with 20 MPH headwinds.

2011 Gmc 2500hd Denali crewcab 4x4 with about 20k miles on it. all but perhaps 2000 of those miles are towing a 20 foot livestock trailer that weighs 6- 12k depending on load at time - lifetime average 14.3 mpg.

First 500 miles with no load was seeing 18-19 mpg.

1996 Chevrolet 3/4ton Silverado Extended Cab 4X4

20 MPG unloaded straight freeway

17 MPG all around (daily driving)

Just a little over a week ago finished 2,500+ miles through the Great Basin and much of SW US. Maiden Voyage...Checked each Tank load actual measurement fuel and miles traveled against the 2012 F350 4x4 6.7 L Diesel fancy Average Miles per Gallon Digital Gauge with our Eagle Cap 950 pretty well loaded down. Mileage on the Digital Gauge seemed to average about 1 MPG better than the Actual Computed mileage 14.5 to 15.5 MPG actual, mostly dropped to 14.5 average when we were bucking quite a head wind. it was not uncommon to see 18 to 20 on the Averaging meter at times...
We mostly ran 11.5 to 12.5 mpg with the 2000 F250 4x4 V-10 we just sold to some great folks as there new to them camper hauler.
