We have a 60 gallon RDS tool box/fuel tank from Northern tool. I installed a solenoid switch and a inline fuel pump with a filter. This seems to work just fine as it lets me run about 1000 to 1100 miles before filling up (sometimes needing a bank loan for the fill up).

Like Dave we had a Titan on our other truck, but as the years went buy and the back and kidneys got worse we felt the factoryHave a 67 gallon Titan Replacement tank on the 450. I weighed the pros & cons of more capacity vs. more weight and went with the Titan. Works for me and I don't lose any bed space.
Titan has said they will have their 52 gallon poly replacement tank for the 2011 F series short box truck available sometime this month....This is the only complaint I have with the new truck. 26 gallons of fuel is not enough for this truck.
I was leaning more towards the titan rather than the transfer flow tank. Does the tank screw up the trucks computer or is there a fix for that?
