Just finished installing a 37 gallon transfer tank in the bed of my truck. I used the RDS gravity feed kit to hook it into the main tank. I added a simple fuel filter for now, I plan on adding a water fuel separator later.Only thing I didn't like was there isn't a lot of room between the top of the flow control valve and the bed. Other than that it was a pretty easy install.
This is just me, but since your transferring the fuel into your main fuel tank...no real need for a secondary water separator. Assuming your using Racor (OEM) filters in the HFCM, it would catch whatever water there maybe in your fuel system. Yeah, a second water separator would be nice, but you could get away without it is what I'm suggesting.
Well, my main concern was that the factory tank is made of plastic and it doesn't create any condensation during rapid temperature changes. But, the steel transfer tank will produce lots of condensation during temperature changes. (mainly cold to warm)I run the correct fuel filters. But I figured I might as well add another fuel/water separator to the system for the added security. I'd rather spend a little now on preventative maintenance, as opposed to spending a lot later down the road for repairs.

The chassis cab trucks have steel tanks...but they're lined with coating that has been an issue in the past. With that said, I'm not aware of any unusual condensation issues with the the chassis cab trucks.

While I agree with your theory...I don't think it would as big of as a deal as you think. Especially if your doing the routine servicings...which should include draining the HFCM in between filter changes.
Just wanted to update this thread with the changes i have made to this setup. I added an electric solenoid shutoff valve to the tank which is wired into the #4 up fitter switch and i also installed a gull wing weather guard truck box that completely covers the tank now.
The solenoid shutoff valve is actually off of a chemical sprayer that my father in law uses to spay his fields. We bought a brand new one and wired it into the auxiliary switch and it works great. I will add a manual valve into the mix later so i can shut off the fuel in case the electric valve fails. The valve we used is part #2202A "Solenoid Shutoff Valve" in the picture below, it set me back about $54.
Nice. To the OP, you are wise to have the extra filter on the secondary tank and a water separator. The problem is the metal tank, and the empty non fuel filled air condensing water into the fuel. This is especially true if the tank is not used regularly, the air space is not filled with fuel most the time, or if the fuel sits for longer periods of time amd it will make some water in the fuel over long periods of time.
