I decided on the transfer flow but am now finding out that the largest tank I could get in the bed with my Bakflip bed cover is a 50 gallon model. So now the search is on for something that is quality and at least 75 gallons. Thanks for any knowledge you have in this area. Dave

I've got a 50 gallon tank off of one my old Deuce and a Half.
Fits nicely under the tonneau cover. I could probably fit two of them in there and still have the companion 5th wheel installed.

Have you check out the tanks at northern tools?

I had one custom made to utilize the empty space under my roll-up tonneau cover. Costs $400 and holds 30 gallon, which is all I wanted it to hold.

Thats the brand (RDS) I purchased only I bought my directly from the factory which is located in Florida, its a 100gal tank with a nice big tool box on top. RDS also sells a kit that lets you tap directly into the filler neck which supply's you with a constant fuel flow until the 100 gals is going, I installed an in line shut off valve in mine so I can turn the flow off anytime I need to, so far its worked flawlessly and Ive had it since 2005.

RDS 48 gallon fuel tank that is gravity fed into my stock fuel tank filler neck. I have had it on for a few months now and have no complaints other than they shouldn't have the drain hole facing the tailgate and now I have to fab up a shield to protect the shut off valve and line from the random things that get put in my bed of my truck.

RDS 60 gallon tool box/tank with gravity feed kit. Bought it from www.Nationwidewholesaledirect.com They were cheaper than Northern

RDS 30gal, under my saddle style tool box. But I run a kubota generator off of it, not my pickup.
