I second BDowse comment on DEF, don't try to cheat it. My F-250 6.7L DEF gauge had two modes, Full and less than half full. Again, another 'what are you thinking Ford?'. I recently sold the F-250 with 150,000 miles (mine was a lemon but that is a different story). Do not run out of DEF. And expect to use almost twice as much pulling a load. I could usually go 5,000-5,500 miles, unloaded, before I would get the first 800 mile DEF warning. I pull every summer in Montana, Idaho, Wyoming (lots of mountains). My DEF tank before warning usually was about 3,500 miles. I always tried to keep it toped off as soon as the indicator said less than half full. And always carry a spare 2.5 gal just in case.

A FYI: If you do run out of DEF do NOT shut your engine off till you get more. If you run out the engine will limit your speed you can go. If you shut it off and then try to go again it will limit your speed it becomes a non functional rig. This may have changed in the 2nd gen 6.7L. Also, if you have a DEF pump failure (I have had 2 of these), or the vent line check valve to the DEF tank becomes inoperable (same symptom of a failed DEF pump) then your truck will not punish you as if you cheated the DEF level and ran out of DEF. It can tell the difference but it will give a you warning light and punish you a little bit. Your fuel mileage will get higher and you will notice about a 20-25% loss in power but still maintain a high way speed. I have had to drive pulling twice in this mode in the last 4 years out West. Try to find a dealer who has a $1,200 replacement in stock out West, not going to happen.

Enjoy your torque, you will love it. Just keep the oil, fuel filters and air filters super clean and try everything possible to stay away from bio diesel. In 150,000mi I went through two EGRs because of that stuff. It is like cholesterol to your artieries and almost as fatal.

Towing with a Ford 250

I want to say that we too get the range of mpg that you report with our Ford 250/6.7L TD. I admit that I check mpg rarely as "it is what it is," and we can generally not be concerned about the costs of fuel. We have a 2011 model which finally passed 23,000 miles this month. Once measured a bit ago we were getting @ 19 mpg driving mostly "around town." Towing our 23'Internationl Serenity at moderate speeds, 60mph, fuel consumption didn't seem materially different from non-towing use. However, driving at 70mph made a noticeable difference. Actual numbers are unknown.

These comments have suggested we monitor fuel consumption more and carefully. This month we will camp a couple times. I will check the fuel usage and report.

Cheers to all and thanks for great comments.

2013 F250 6.7L, crew cab, short bed pulling 2013 International 25FB. Consistently average 12.5 mpg when towing at posted speed limit. Pretty much stay at 70mph on the interstate even if posted higher. We live at 7000' elevation so its always long climb coming home no matter which direction we are coming from. Most of our trips are in the mountain west, Colorado, New Mexico, Utah and Arizona - 12.5 mpg has been the average.

I have learned to use Gas Buddy to plan fuel stops and then go to Google earth to look at each station to see how big the fueling area is and which side of the road they are on. The better half can usually only handle about 250 miles before requiring a break so stopping every 3 or 4 hours isn't really an issue for us, but finding a fuel stop on the back roads that doesn't require contortionist moves with the Airstream in tow can be a challenge.

Having said all of that, I would like the peace of mind a larger tank would provide. I have cap on the bed and a bed slide, which I love, so no room in the bed. Does the Titan 50 gal fit under the truck or in the bed?

Titan fits under the truck. It replaces the existing fuel tank. Here's a link to the Titan website to the page with the Chevy and Ford tanks:

Titan Fuel Tanks Website

Price of the tank ordered from Titan is noted on the web page. My Ford dealer quoted me a price of $1980 plus tax installed on my 2011 F250 Lariat 4X4 diesel short bed, crew cab.

Here is a link to an installation video:

Perfect, thank you Chuck. I do have the FX4 package so this will work. Hopefully my Ford dealer can install as I don't want to do anything that would void the warranty.
