Are you sure that 250 number isn't for gas while the 350 is for diesel? I don't really have a dog in this fight, but I know I'd hate to strap 22,000 pounds behind an F350 with a 6.2 gas and 3.73 gears and try to get somewhere.

I got mid 11's with my 6.7 pulling my 8K TT at 65. I'd check that mileage a few more times if I were you before getting too excited.

The OP was for a comparison of 6.2L Gas F250 to 6.7L Diesel F250.

Later posters recommended going to a F350 Diesel.

I believe I posted 6.2L Gas F250 to 6.7L Diesel F350 info.

ERROR * ERROR

Looking again at the towing guide I noticed that The 3.73 Geared 6.7L SRW F350 is not made; has to be a DRW to get a 3.73 F350

The Max Combined Wt for a 6.7L Diesel F350 SRW is 23,500 Lbs with the available 3.55 Axle Ratio.

A 4.3 Axle Ratio on a 6.2L Gas SRW F250/F350 is rated at 22,000 Lbs.

Me too (on the flat, at lower elevations, on an Interstate, with the wind and with a 7K TT and combined weight of around 16K ).


Average coast to coast East bound on I-5, I-10 and I-75 is around 10.5 MPG
I-40 a bit less and I-80 a bit less than I-40.
(my wife makes jewelry and we haul it and her supplies and tools from Norcal to Fla and back when we snowbird)

The engineers at Ford when the 6.2 first came out clearly stated that the 3.73's were very good for towing under 10k anything over they recommendation was the 4.30's. I reread my original post above and it says I had issues which I meant to say no issues. The truck never went below 3rd gear and while I am not sure on the total GCWR I can make a close guestimate based on knowing the base weights and I believe we were a bit over 17,000. But if you are like many RVer's and have loads of money to spend go get the 6.7 because at the end of the day the 6.7 hauls more and if you don't like the sound of a V8 making power then the 6.2 like all modern gas V8's will make you unhappy.

I can say that I have owned the F250 with the older model large gas engine. It did a great job and I got around 11 miles to the gallon period. The TT weighed in around 8,000 pounds. I bought a new TT that would weigh in around 9000 and pulled with a F150 I traded the old F250 to. Big mistake. I was at the upper end of the range and it was a chore on the road. The truck would do it, but I knew the camper was back there. Bought a 2011 F250 Diesel and love it. Pulled the TT and averaged around 16 miles to the gallon. 19 without pulling a thing. Could accelerate past anything at 70, and could get up a mountain and gain speed even on a good steep grade. Just sold the TT, got a 05 Gtown XL, but am keeping the truck.

I hate to rain on your parade, but no one is going to believe you get 16mpg pulling a 9K camper.
