Good job and good luck on your new truck. I pull a much heavier 5ht wheel and it is like nothing is back there. Glad you found that locking 6th gear out on the hills. You also need to read about and possible use the Tow Haul switch on the drive lever. You probably know about it being you had a 6.0L like I did.
Keep us posted on future trips.
I will be startinga 2,700 mile jorneyt pulling my trailer and should have a good review when I'm done.
Here is my first review pulling.
OverviewJust got back from a 700 mile trip pulling a 5th wheel trailer and wanted to update you on the performance and mpg on my new 2011 F-250 6.2L. Truck had just went over 1,000 miles before trip.
Truck - 2011 F-250, 6.2L, LB, SC 2x4, 3.73 rear
DetailsThis trip was mostly on Interstate highways and I ranged speed from 55 mph to 70 mph.
I kept transmission in D and did not manually select or remove any gears.
The trip was from Phoenix Arizona to San Diego California and back.
Most of the trip was level except for the climb at Palm Springs westbound.
Westbound I had a headwind of 8-10 mph which hurt mileage.
In Arizona I drove 65 -70mph and in California 55-61 mph.
AC was always on for the entire trip.
My 30ft 5th wheel weighs 8,800 lbs total. 7,500 on the 2 axles and 1,300 on the hitch.
Most of the trip I stayed at 61mph and 1600 rpms which was the sweet spot for the Engine & Trans.
All of my fuel was 87 octane with 10% ethanol which I didnt like but that what was available.
Outside air temp ranged from 65 to 90 degrees.
When filling with fuel I pumped until the automatic nozzle clicked off and I went up to the next full dollar amount. This makes all fill-ups consistently close in being the same.
My observationsTransmission took at least 5 miles to get up to 165-175 degrees.
Transmission temperature ranged between 184 199 degrees.
Engine had plenty of power and torque in all speed ranges.
Transmission did not miss any gears and was very smooth shifting.
The exhaust sound is good at cruising and downshifting sounds great!
Pass a few trucks pulling trailers, Dodge Cummins, Ford F-150 and even an F-250 Powerstroke.
Engine response was very quick when I needed it.
Mileage westbound with headwind was 8.7 mpg. (Hand calculated)
Mileage eastbound was 9.3 and 9.4 mpg on two fillips. (Hand calculated)
When hitting the headwind the truck liked 5th gear but quickly changed to 6th when wind decresed.
My thoughts and conclusionI converted from a F-250 6.0L Powerstroke diesel to the 6.2L gasser.
Im very happy and have been pleasantly surprised in the performance of the engine and transmission.
I hope with time and miles my pulling mpg may raise and reach 10mpg which I think is possible.
The continental tires were good and quiet on the highways.
Hopefully this will give you a better idea of the performance of the 6.2L gas engine.
