Planning to purchase a new Ford F 350 with the diesel engine, crew cab and short bed. It only comes with a 26 gallon fuel tank. I would like to purchase an auxiliary fuel tank. Do any of you who have experience with these kinds of matters have any recommendations for me? Thank you in advance for your assistance.

Don't know what kind of MPG you will be getting while towing, but I average 11mpg, which means I have to refuel about every 3 hours.

It is my belief that most drivers pulling heavy fivers need a break every 2 or 3 hours.

We have a below-the-bed tool box mounted in front of our hitch. I keep four 5-gallon plastic cans of diesel when traveling. There are times when the plastic cans stay empty and there are times when I have them all full. It just depends on what part of the country we are in, where some of the fuel stops are, and at times prices.

On a recent 7,000 miles trip out west I utilized the extra fuel twice.
Total cost of my add-on feature to carry extra fuel was about $30.00.

I guess my point here is make sure you really have the need to be running down the road hauling an extra 30 to 40 gallons of fuel before spending all that money for a modification. Remember you are also adding another 200 to possibly over 300 pounds to your TV that could slightly reduce your MPG.

Stopping every 2-3 hours sounds about right, maybe a bit less. But if you carry enough fuel for 3 hours, all your "rest" stops are in noisy, crowded, smelly fuel stops. Personally I'd rather stop in a pleasant rest area, or even just pull off the road at a park. Fuel stops just aren't good rest stops.

Auxiliary fuel tanks mean you can stop when you want to stop, not when your fuel tank wants you to stop. It's something I'd get just to make life more pleasant.
