yourpcgeek49 Posted October 22, 2014 Report Share Posted October 22, 2014 In drawing up a budget one of the major components is the cost of fuel. I am planning to purchase a 350/3500 class dually to pull our 5th wheel (max trailer weight 16,000#). I know that there are lots of variables, but am looking for what others have experienced both when pulling and not.

Guest Pensauncola Posted October 22, 2014 Report Share Posted October 22, 2014 10 to 11 mpg if kept under 60 mph and reasonable wind and terrain. Link to comment Share on other sites More sharing options...
TXiceman Posted October 22, 2014 Report Share Posted October 22, 2014 Just a bit heavier, 62 to 63 mph, we generally get 9.5 to 10 mpg. Last run from Atlanta to Knoxville, we got 10.5 mpg.

TXiceman Posted October 23, 2014 Report Share Posted October 23, 2014 To add more info, we have dropped to 7.8 mpg one time bucking a pretty strong head wind (20 mph gusting to 40 mph). I could not slow down much as it dropped the engine off the torque peak and it wanted to downshift constantly.

Chad Heiser Posted October 23, 2014 Report Share Posted October 23, 2014 With my 2007.5 Duramax DRW pulling a 16000 lb 5er, I averaged about 9.5 mpg overall (sometimes better and sometimes worse dependant on terrain and wind). I am getting about the same to slightly better (9.5 to 10 mpg) with my 2000 T2000 with Cummins N14 and autoshift pulling the same trailer. 2000 Kenworth T2000 w/ Cummins N14 and autoshift 2017 DRV Mobile Suite 40KSSB4 with factory mods, dealer mods and personal mods - now in the RV graveyard 2022 DRV Full House MX450 with customized floor plan 2018 Polaris RZR Turbo S (fits in the garage) 2016 Smart Car (fits in the garage or gets flat towed behind the DRV when the RZR is in the garage)My First Solar Install ThreadMy Second Solar Install Thread & Photos and Documents Related to the buildMy MX450's solar, battery and inverter system - my biggest system yet! chadheiser.com West Coast HDT Rally Website Link to comment Share on other sites More sharing options...
k4rs Posted October 23, 2014 Report Share Posted October 23, 2014 We usually get 16-18 solo and 9-11 towing 14,000 pound 5th wheel. Our typical cruising speed is 55-60. The worst mileage we ever saw was 7 mpg while driving into a 40 mph headwind for an entire day. Safe Travels...

missourijan Posted October 23, 2014 Report Share Posted October 23, 2014 Like others we get 9 to 12, depending on road & weather conditions. Our 5'r weighs 19,400 and we drive 59-61. We've checked fuel costs at 65 and get better mileage at lower speeds. Jan & Thomas 2012 Drv Mobile Suite 5'r 2012 Ford F350 Super Duty Link to comment Share on other sites More sharing options...

If you base your budget on 10 MPG for all miles driven you will be pretty close, and maybe enough left at the end for dinner, if you're lucky.

yourpcgeek49 Posted October 23, 2014 Author Report Share Posted October 23, 2014 Thanks to all who responded. I had been figuring around 10 mpg, but wanted some confirmation that my assumptions were correct. When discussing the budget with the DW, you don't want the wrong version of assume to show up! LOL!

RBH Posted October 24, 2014 Report Share Posted October 24, 2014 07 f350 6.0, approx. 11mpg flat, no wind towing 14,000 lb 5er, 17-18 solo. 05 FL M2 Cat C-7 8-9 overall. Both myself and DW much happier with the security of the M2 even with the mileage penalty. Would never go back to LTD with this trailer.

BrianT Posted October 24, 2014 Report Share Posted October 24, 2014 I plan on about 9mpg. I've gotten a little better than that but I don't think I've ever gotten any worse. It's hard to predict things like tail winds or what traffic might be doing. Terrain, maybe somewhat predictable (mountains vs plains). It helps having about 130 gallons of fuel capacity onboard.

justRich Posted November 16, 2014 Report Share Posted November 16, 2014 2015 6.7 diesel dually - new truck. . .just hit the 1000 mile break in mark and then loaded the camper and headed south. Now have about 1500 miles with the camper loaded and it looks like it will get about 11.6 mpg at 62 mph average. Speed of course, is the biggest factor since we're pushing a barn door side-ways down the highway. Also noted a driver dragging a 5ver reported on the ford-trucks forum about the same with his identical truck: 11.6 mpg diesel with varying road conditions over a long haul. Casual cruising without the camper at 55mph it will get about 20+ mpg. Bye the way. . .it has massive power! Quiet too. It's light years ahead of the older trucks. ~Rich Link to comment Share on other sites More sharing options...
