The heaviest I tow is about 7.5K with an enclosed trailer. The steepest hills that I've climbed were a breeze. I was easily able to keep up with traffic on the interstate (65-70 mph) and was able to pass a few. I was in 4th gear on the toughest climbs and running about 3500-4000 rpms. The engine wasnt screaming but did have a nice exhaust note. Shifting was smooth and effortless with the tranny. Going down hill was just a good.

As stated earlier I havent had this trailer with max load (7.5K) in the mountains yet, so I'm just talking about normal hills. Now, I have had smaller open trailers in the mountains that I wrote about already.

Maybe someone who has had their 6.2 in the mountains pulling moderate to heavy weight can chime in.

"Plus you will have a truck that you won't be scared to own out of warranty."
My sentiment exactally.... My 03 6.0 f250 sc is out of extended warr.with 50k mi. Although no prob's except for that oil sensor switch under the turbo it's a good piece of equip. If I trade now for a 6.2 I just might get a little over wholesale - woop de doo !
Thanks for the tow info - seems like a 6.2 will haul a 9k lb. cedar-creek 5th with
moderate performance. Ditto's too on loosing the ULSD fuel at $3.30 and maint.

Ok, just towed the trailer from VT down to NC. Hilly I-87/287/78 across Pa. down 81 over to 95 then 85 to Durham.

70 mph and got 9 mpg. Funny thing was, I thought as I got on the flatter I-85 road, mileage would really go up compared with thehilly I87-78 but only went up about .5 mpg. 8.8 up north and 9.3 down south.

Not much difference between 60 mph and 70 mph.

My take: My truck just plain gets about 9 mpg when I towing my trailer.

Power was pretty good but I think 5 Star will be getting a call.......

Not unhappy, just the facts.

Great first pull writeup Front Runner.
Now that it is 4-5 months since your initial trailer pool have you noticed any difference in your mpg city or highway empty?

I have a 03 F-250 Powerstroker and just ordered a new '11 F-250 with the 6.2L and your writeup helped me for sure as I pull a 5th wheel that weighs fully loaded about 8,500 -9,000 lbs depending on how much clothes my wife takes. :-X10


Anyway I now have to wait a few months before the truck arrives.:-X09

Im getting out of F350 2008 6.4 psd because of worries with future repairs. I pull a 5000# trailer 7 times a year. i was looking at at the F150 with the 5.o , but I really think I want to stay with a super duty F250 with the 6.2 gasser, but dont know if I will like the gas mileage when not towing. driving back and forth mostly not towing would be nice with better mpg..more money for beer

First off, thanks to the OP and others for posting their real world experiences with the 6.2L. I too am a current F350 6L PSD owner. Mine is a 2006 and will be off warranty soon. The new diesels are way too complicated, so I'm looking at getting a gas F350.

The only thing I'm unsure about is whether to go with the 3.73 or 4.30 gears. I tow a 4 place enclosed sled trailer that is probably about 6,000 lbs with 4 sleds and gear. I also have a fifth wheel RV. Its 12 feet tall. The dry weight is over 7,000 lb and the GVWR is 11,000 lbs. I'm guessing it's about 8,000-9,000 lb loaded up. I'm leaning to the 4.30, but everything is within the tow rating for the 3.73. I'm not sure what to order.

4.30-no doubt.

4.30 gears would be better for you.

4.30 it is. Thanks.

My 5th wheel is between 8,000 and 9,000 lbs loaded and I'm going 3.73 and I'm confident my new F-250 with the 6.2L will pull it with no trouble. The 6 speed transmission with help. I'm trading in my '03 F-250 6.0L PSD also.

What kind of mileage without pulling the trailer?

Who you asking and which truck?

Any one with a 2011 superduty 6.2 L gasser. Was jsut wondering mileage without pulling anything. Seem to be all over the map..Thanks

Greg,
I have been reading everything I could find info on the mileage for the 6.2L gas. I have read it is all over the map and what I have concluded is a heavy foot will kill mileage everytime. Stop and go will also.
I read that at 55 MPH you should get reasonable highway mileage of 16 mpg and if you increase to 65 MPH your empg will decreases by 15%. So my conclusion is the truck will pull lots of weight and you must find the sweet spot between economy and pulling a trailer. These trucks are designed for power and torque to pull heavy loads.

With that said I suspect I can get 12 mpg pulling my 8,500 lb trailer on a flat highway at a safe speed. If I was empty on the highway I suspect I can get 16 MPG.

Keep in mind that learning to drive for economy is a true art form and will never get it trying to race around town spinning wheels and gunning it.

FYI I have been trailering since 1991 so I have a few miles under my belt. I have owned gas as well as diesel truck.

Thanks
So let the flaming begin. :-X01

The 16mpg empty-no problem.
But what kind of 8500lb trailer are we talking about?
