I bought the 2015 the day after I towed my new to me 5th wheel toy hauler home as I was going on a trip with the RV later that week and knew I would hate myself all the through PA with the gas truck. I still feel more comfortable with the 2001 but its been a 14 year love of the truck.......I think its time to let it go and be faithful to the new big guy.



DIESEL HAS MY VOTE

Ok...nobody quote me here...

That's a tuff looking Chevy...didn't hurt tooo bad.

The only Dodge 6.7 I've driven was a 1 ton dually. 65mph on flat ground and it wouldn't do better than 12 based on the DIC. This is a pre DEF truck and is obviously DRW- do those 2 things really make that much difference on the 6.7 Dodge????? I could understand a few mpg, but almost half???

On my GM trucks the best I ever saw not towing with the 2001 gas was 11.2 mpg and 5.7 mpg towing our 40' long 12' wide 14,000 lb catamaran. With the new diesel truck it show the best recorded 50 mile mpg was 20.6 not towing and the worst was 10.6 towing the toy hauler.

One of the things I learned with my 2013 RAM 6.7 DRW is that the DIC is off by an average of 2-3mpg when I compare it to my fuel logs. Around town, the DIC typically gives me 17-19....fuel log says 15-16. Pulling my appx 17,500lb 5er, the DIC indicates 11-13 whereas my fuel log has it at 10-11....

The dually probably has a much taller rear gear, and dual rear wheels don't help either. Do you remember your rpms at 65 mph? Mine runs about 1400. I do not go by the computer. The calculator on my phone, fuel pumped, and miles driven give me a good picture of what mileage I'm getting. Pulling about 7K pounds in mostly flat country at 62 mph and yes, the figures are right. The trailer's just not a strain at all.

The computer shows better mileage, like bass-boat speedometers... they're for sales, not for actual use. My last bass boat would bury an 80 mph speedometer, but the GPS showed me I was actually running 75.

Dealer let us take a new loaded Lariat Super Duty out for a day pulling our trailer and it was sick the way it handled my trailer.
New trucks are supposed to be driven 500+ miles before first tow... Just another reason I won't buy a "new" truck with more than a few miles on it... How do I know what the last guy did to it test-driving it? WOT? 10,000 lb. trailer? Uneven R/R tracks at 60 mph? No thanks...

that is just to set the rear ring and pinion, I know lots of friends that tow heavy from day one and put way over 200k without 1 single issue. Including myself..

Ok I'll say it.

I have come to the conclusion that the 2 main things men lie about are pecker size and fuel mileage.

I have yet to get 14 pulling anything with the three diesels I've owned. I might do 14 or 15 empty. (Hand calculated). 8-11 pulling.

The greenies ruined diesel for the working man with low sulfur diesel and the yuppies switched from beemers to diesels to pull 18 foot boots doubling the demand and bumping the price limits of insanity on new trucks ( and what red blooded male doesn't jones for a new truck).

We are fortunate to be able to choose. Give it a couple years and the progressives will have us bumping 7 bucks a gallon and buying back our 1tons for yugomatics.

The most realistic answer I've ever heard is when I was filling up next to a monster diesel pusher. I asked what kind of mileage he got and he said he averaged 11 mpg...5 mpg in town and 6 on the hiway.
