    Just throwing this out there. Would it be possible to have a fuel cell in the bed, wired with a fuel pump, and plumbed to pump fuel into the filler neck for refueling in the go? The delema for me at least would be getting fuel into the main tank safely and reliably. I just drove to Moab last month from Dallas, and the extended range would be nice, as well as I took a route that didn't lend itself to many places to stop. (Not an issue if you stop when you can as opposed to when you have to. , but still.). System could be removable, and it would eliminate the need to manually fill from a jerry can.

    Another option would be to simply run a line from the cell and manually fill up with a siphon pump or if you were fancy a fuel pump just because.

    I remember having dual tanks on my moms old chevy truck and flipping a switch to swap tanks. It was convenient because we had horses and we traveled a lot in the summer for trail riding competitions.

    I knew a guy who installed a 'transfer tank' opposite his regular tank on his old hilux 4x4. Of course he had to re-route his exhaust to the middle (next to the drive-shaft ! ) . A neat solution that was almost invisible from outside the truck. I don't recall whether he rigged a pump or a syphon.

    Another old solution, I recall, was installing a tank where the spare tire used to be.

    I'd be ok with a bed mounted setup. Although the spare location is nice. Maybe cut a hole in the bed for a flush mounted filler Location. I was going for simplicity. I don't mind the cell in the bed.

    The real trick is getting the fuel into the main tank w/o throwing some sort of code (pressurized tank and all). And I wouldn't want to compromise the tank itself. Just the filler neck. How about a small fitting that a hose can be threaded onto when in use and capped off when not in use? Maybe a check valve in line somewhere to prevent back flow and hold pressure too.

    Maybe the tanks would have to be vented or have a return line of sorts too, to allow for air displacement to move between tanks while filling. Damn that just got too complicated. Lol...

    Use a junction pipe in the fill hose. Get/build one that has two ports. Place them so one is on top and one is either on the side or the bottom. Run two hoses to the fuel cell (which generally have a vent/return fitting on top). Use an aux fuel pump (transfer pump). As you pump fuel, it will vent from the OE tank to the aux. MAKE SURE YOU USE GROUNDING STRAPS.

    The devil is in the details LOL!

    If you are just going for a transfer tank in the bed, it can be fairly easy. Farmers do it all the time. Just run a hose off the pump and stop to "fill up"/transfer the fuel. Doing it while driving is when it gets complicated.

    Just get a dual tank transfer switch Like what the trucks with dual tanks use

    Just like you had in the Chevy

    I would tee in the line behind the fuel filter .

    No codes no problems

    When and if you want to remove the fuel cell just disconnect the line at the tank plug to keep the dirt out

    If I was wanting to haul extra fuel but not all the time be simple to use

    This might be the best option. I suppose it would be nice not to have to stop but it wouldn't be a huge deal. Just get a bigger fuel pump to speed up the process. Just have it in when I need it.
