20,000 miles and....

The truck hit 20k this A.M., just finished a 750 mile trip pulling a 14-15k fifth wheel at 65-79 mph averaging a consistent hand calculated 10-11 mpg. I am repeatedly surprised by the trucks power, and still "breaking er in" with wot up inclines, and often wot after the truck is rolling from 30 mph plus with the fifth wheel. Pulling I have not noticed much mpg difference from 60-70, hence... 70+ seems to be where I end up.

I anticipate break in to be between 60 and 80,000 miles, will determine break in by the 6.7 obtaining the relaxed lope at idle that accompanies the well used diesels, any other ideas on break in clues?

Driving: 2011 Pale Adobe...F-350 CC 6.7 FX4 3:55-Locking Rear End-Dual Alternators-premium Lariat, moon rf, added wheel flares, 2-tone black base

Picked up 4/29/10 as of 06/20/2012 109,000+miles

Curious about your truck. Is it SRW or DRW? LWB or SWB? Did you get the factory hitch prep.? Have you pulled much in the mountains with it? What is the mileage running empty? I'm getting real close to ordering one and trying to make up my mind on a few things and you seem to have the most mileage that I have seen anyone post so hence the questions. Is there anything you would do different about the truck if you were ordering one today?

Don't worry about the Mule, just load the wagon.

No fuel additive, it's a short bed cc F-350 SRW no factory gooseneck. Running empty mpg depends on what I want. I can baby it around town and eke 19 mpg even with stops, take offs. Not my style. On the highway, best empty is 18 mpg at 75, other times 16-17 mpg running same speed at different times/locations. What would I do different if I were to reorder the truck? Not much if anything, the fifth wheel? I did not realize how big it was until I hooked up!! First 100 miles I wondered if I should have got a dually, second hundred....realized if my tires were good, and low pressure warnings are working, keep a safe distance and a good eye on the road... I had nothing to worry about. I have pulled on flat, up grades, the truck has never faltered, heated, and at the same time has warmed,or cooled my arse when requested!! I am GLAD I ordered the F-350 over the F-250, the old adage holds true, I'd rather have the extra capability and not need it, than need it and not have it.

Yea, the power over my '08/6.4 is way different and the tranny is sooooo much better. I love the manual feature!!

I just did a 550 mile round-trip to Padre Island over the weekend pulling my 40ft 14K 5er and got 12.4 for the trip. Not bad!!

I love this truck!!

Did you eventually have to turn the tire monitoring system off when loaded with the 5th?

What size wheels you have on the truck?

Thanks for the info.

I am trying to figure out exactly what I want. I sold the truck in my signature 2 yrs. ago and bought a 06 Megacab 5.9L. I was happy with the way the 01 Ford towed for the most part. The Dodge has it good points and bad. The Cummins pulls very well but the truck itself is not set up optimally for what I need due to the lift on it. I want stability when towing my 5er. The problem is that the DRW Ford fenders haven't grown on me yet and the wife wants a short wheel base. I'm leaning toward a compromise (F350 LWB SRW), after all, I was happy with my 01 until I blew the first motor.
Again, Thanks!!!!

Just hit 1,000 miles this am. Haven't had the pleasure of towwing yet. The hitch is still in the mail. I had to change the whole set up for the 2.5"er, mount, ball, and pin but I like what someone else said, no one can borrow your set up this way. I ordered the reducer though, that way I can borrow someone else's set up I also had to order the reducer so I could put a hitch cover on. Anyone find any cover that fit the stock 2.5"?

I can't wait to start rolling the miles on. I am normally a high mileage driver for someone who doesn't work out of their truck.
