Hello,
We just bought a Ford 2022 Diesel F350 KR crew cab short bed. I would like to add a external 40-50g slim tank on the bed behind the cab with gravity fill only. We will be towing a 5th wheel.
Any recommendation on what to get?
Not necessary but any tank out there that will work with a hard bed cover?
Thank you
MC

Contact Transfer Flo in California and talk to them.
I referred a friend to them, he conferred with them, purchased it and they shipped it to him, and a local garage installed it for him. This was a replacement tank, larger of course, that replaced the one he had.
Now I'm trying to get him to buy one that sits in the bed of the pickup, low profile.

Thank you.
I was told by the dealership that a low profile in the bed will not void the warranty. I want to keep it simple.
I have a friend that installed a DEE ZEE but I was wondering if there was anything better.

I bought this one.
While it says 60 gallons it will only hold approximately 53.5 gallons.

I have used both KSH and Transfer Flow. The essential difference is that Transfer Flow automatically pumps its fuel into the main tank as needed. With KSH you manually switch between truck's tank and the KSH tank. (You don't want either tank to run dry.)
I liked the Transfer Flow because you can relax and forget about how much fuel is in which tank -- you just monitor the combined total.
Transfer Flow has a number of authorized installers around the country.

The transferflow system sure appears to complicate what is easily accomplished with a gravity system with a check valve.
But I’ve used neither, so simply speculating.
What is the advantage of say the transfer flow “computer controlled system” vs a typical automatic fill gravity system?

I installed an Aluminum Tank Industries 46 gallon auxiliary tank in my truck bed. With cap, it measures 19" tall. My tonneau is a tri-fold and sits on top of the bed rails. I installed a kayak hatch in the tonneau to access the filler cap. Works perfect.
I expected the tank to pay for itself by the middle of next year by reduced cost of where I buy diesel. With the 67% increase of diesel in my area, not having to fuel on the road has already offset the tank cost. The tank was worth it from the outset due to the added convenience. Haven't fueled with the trailer attached since the tank install.
