fuel mileage

[Denlor]

what do you get pulling a 12,000 lb. TT with your 5.9 Cummins?

[cacoon]

I have a 06 Ram 2500 diesel. My trailer is a 2012 Keystone Springdale 281bhs. I have consistently averaged 10 mpg. One trip out of many when I had water tanks full and another 60 gal of water in truck I got 6mpg. I usually travel about 60 to 65. If I push 70 mpg goes down quickly.

thank you ripperoo: as stated just wanted to know what others get as I thought my mileage/gal. was out of line so I did some more calculations and yes I was way out of line. I now am at a 11.5 to 12 and I think that is not bad. Maybe the fuel between the US and Canada makes the difference. We have fuel with very low sulphur and low Bio.

I just finished a trip to the Black Hills with a 7k FW. I got 14.8 with my 05, 2500, 5.9, 3.73 auto. Best buy I ever made. My 01, 2500, 5.9 gas gets 8 to 9 hooked on to a stock trailer with 10k gross.

Too many variables. You get what you get. If your worried about fuel economy, then maybe you better sell your RV and truck and buy yourself a hybrid.

Wow, absolutely useless answer. He didn't ask your opinion, he asked what those who have 5.9 Cummins engines get for mileage.

OP, if I had a Cummins, I'd tell ya. And I'm sure it would be better than the 8.8mpg I get out of my gasser.

'06 5.9 CTD towing about 10,000lb TT. 10-11 at 60-62 mph. 1700 rpm with 3.73. Might see 12mpg on a good day. Have gone as low as 7-8 bucking strong headwind. 60-65 mph seems to be the sweet spot. Would, no doubt, do better at 55 but, never tried it. Mileage drops significantly at 70 and above.

I have a Dodge 2500 towing about 10K and I get 10 on a good day. We've hit as low as 7 in the hills. Towing a utility trailer or boat, I get about 15. That huge trailer drags quite a bit of wind.

I can't imagine anyone getting anything close to 15 towing a TT or 5er.

14K VERY Tall 5'vr.......10 to 12 mpg..........4:10 rear end

You asked: "what do you get pulling a 12,000 lb. TT with your 5.9 Cummins?

Sorry, I have to doubt both of these claims.
But truthfully, I am getting around 21 with my Duramax..honest.

Correct me if I'm wrong, but all tvs towing a fiver or a standard TT all average around 10-12 mpg because of wind resistence.

Have a 12k FW pulled with an 06 Cummins. Get right at 11 mpg hand calculated. The digital lying meter says 14 mpg. If your really getting 15 mpg+ you are doing outstanding. No way anybody is getting 17+ towing a TT/FW.

Now same truck with an 18k# gooseneck horse trailer I average about 13mpg. That trailer is narrower and shorter than the FW. On long distance highway towing with trailers inside the ratings of the truck it is more about wind resistance than wieght, as you can see by my example.

Sounds good midnightsadie. I am getting between 15 and 16.5 but have heard guys say they get 17-19 and was thinking I had a lemon. Maybe as stated I should buy a hybrid (donn0128) but do not want to go down in status. Love the smell of diesel.

[midnightsadie]

I had a 2001 5.9 pulling a 7k boat 14teen most the time. on the free way. running 60mph.

was just a question to see what other people got did not require ADDA
