Extended range fuel tanks - who has one?

I'm looking into replacement fuel tanks. I'd like to hear from folks who have replaced the existing tank with a larger replacement. Since I haul a TC, can't use a bed tank like I did when I had a 5'er. Also don't want a spare tire replacement tank...I like having a spare.

Stock tank is 37 gallons. Fully loaded, depending on where I go, I get 10-11mpg. Usually, it's my arse saying it's time to stop and take a fuel break before my gauge says to. But sometimes, it would be nice to have a little extra range.

I've found three so far for my truck, these are the best prices I could find--.
-Titan 67 gallon, ABS plastic, $1409 free shpg
-Aerotanks Aluminized Steel, 60 gallon, $980 + $170shpg
-TransferFlow Aluminized Steel, 57 gallon $1185 free shpg

Any thoughts?

I have had 3 auxiliary fuel tanks from TransferFlow in Chico Ca, that fit and replace your stock tank location. I have a 64 gallon tank in my current 2004 Diesel Dodge 3500. If possible I would drive to chico to have them install it and they can have it done in 1 day. They will also mail the tank to your location and provide the name of a shop in your area that is qualified to install it. I have never had any problems with any of Transfer Flow's tanks for diesel trucks. They are very professional and competent and friendly.
