2011-present 6.7 superduty owners ?

[Hedgehog]

I just sold my diesel pusher motor home and I'm going back to a fifthwheel. Even though I have owned two ford diesels (7.3&6.0), I was leaning towards a gas truck with 4.30 axle to tow my new fifthwheel (Montana with 11,700 dry weight and 2,600 pin weight). The problem is I have to order this truck and there are a ton of diesel powered f350's on the lot. So, 6.7 power stroke owners, how do you like your engines and how reliable have they been. Please post mileage along with any problems to date. Also, I'm looking at a crew cab short bed, how is the 26 gal. Fuel tank for you diesel owners? What kind of range do you get out of a tank, both towing and non towing?
Thank you in advance!

I just bought a 2012 with 32K miles and have only owned it for 3 weeks, but this truck is sweet, sweet, sweet. I have never owned a diesel so it's hard to compare it to anything, but so far it makes me almost laugh and point fingers at my old 2000 Ford V10.

Just turned 90k miles on my 2011, only fuel filters, brakes, tires and oil! It did have a recall for emissions, this was a reflash and I have noticed no difference.

You mentioned 4:30 gears, I believe you wont be able to get that until your in a f450, that trailer you posted will easily be towed by a 350. Don't forget these trucks are 6 speed trans and pull very nicely as all 3 brands do.

What tires did you replace the stockers with? I need some this week.

I've owned a very early 2011, which gave no problem. It was a F250 and I just felt overloaded on the springs not the motor. went to 2014 F350 DRW, and can't believe how well it performs. When urea tank shows 50% low I will add and never worry about running low. I really like the DRW and the long bed. It came with hitch prep, so just dropped in a B&W hitch. Installer took about 30 to put hitch together and install.

Exactly. For 99% of rigs out there you just don't need to go with a deep gear on a diesel. All you're doing is costing yourself mileage. Mine, with 3:55's, does not feel like it's working hard at all with 17-19k behind it.

People get hung up on gear ratios on a diesel truck. You need to know that a diesel engine develops its power at a much lower RPM. You just cannot compare gearing between gas and diesel as there is roughly a 40% difference.

Right on about the 4:30's in the F450. They also come on a DRW 350 if you order the max towing package which includes the 4:30's and the wide track front axle. Also agree that either aren't necessary unless you get REALLY big...

Get a long bed, F350 diesel and add an auxiliary tank of 40 or more gallons. Now no worries about fuel supply.

My 6.7L has been great so far at 32,000 miles and towing near the limits.

If you are thinking about the short bed and get the smaller fuel tank, it will be annoying if you get the gasoline engine since your range will be reduced (plan on the largest tank for a gasoline engine). I think your load out east can be handled by gasoline or diesel but if you plan to travel west often, you will wish you had the diesel if you frequent thinner air.

I just went through a truck upgrade and was considering switching to gasoline from my previous diesel truck, but there were too many limitations for my use to make the switch (GCWR and fuel range). I was looking at the Ford F550 and Ram 5500 and chose the latter, but both brands were competitive.

The Super Duties with gas engines come with 35 gallon tank regardless of cab/bed size.

Fuel tank — 26-gallon capacity (F-250/F-350 137-in., 142-in.
and 156-in. WB with diesel engine)
Fuel tank — 35-gallon capacity (gas engine only)
Fuel tank — 37.5-gallon capacity (F-250/F-350 158-in.
and 172-in. WB with diesel engine, and F-450)

LOL...take ALL comments with a grain of salt....you'll never get anyone on THIS forum to post anything negative about anything they own.

I have a 2012 F350 SRW CC SB 6.7, and of course the small tank. It came with the 3.55 gear which I suspect wasn't going to be great since my current fiver comes in over 15,000 pounds. I was wrong.

I now have almost 55,000 miles, most of which is towing all over the country. My overall average towing the fiver is right at 11mpg. I can average as low as 15mpg with all city driving but generally stay around 16-17mpg when not towing.

The regen does not effect your towing or horsepower at all. You may notice your dash lie-o-meter registering slightly lower mpg after the regen.

I am picky about what diesel I run though my truck. I only buy from places that sell tons of fuel. When traveling in California you almost have to use B20 biodiesel and I really didn't notice hardly any difference with my 6.7.

Don't tow with it, but have the 6.7 in the F550 Plow Truck.

Heaps of power, no problems through some fairly severe usage (although not many miles).

The small tank is not an issue for plowing use, but the 550 I have also came with dual tanks.

After reading jus2shy's post, I realized I worded things incorrectly in my post.

My new Ram does have an exhaust brake. The 2011 Ford was grade braking, but not an exhaust brake. OK, I've confused myself enough.

Have to disagree on your statement of the pre 2015 models not having much grade braking. The feature if amazing and we do a lot of mountain passes in our camping just within our state. Having come from a gas truck with no such braking feature, this is a piece of cake.

I fully agree. The engine exhaust braking on my 2012 6.7 holds speed very well coming down mountain passes. Take comments from a non-owner with a grain of salt.

X 3 for me. Although I no longer own my 2011 Ford with the 6.7L diesel, I felt it was an excellent vehicle for grade braking.

Mind you, I think the grade braking on my new Ram is even better than my previous Ford. But nevertheless, the Ford did just fine.

It's all relative guys. Ever sat in a 2015 Ford with its EB going? Especially when it's revving and the EB is applied, that thing hold the truck back hard. Maybe I could had worded it differently, but non the less, the EB setup for all 3 manufacturers have a much better slowing effect than grade braking alone.
