I've been trying to decide on a fuel transfer tank & tool box to mount on a F450 with a flat bed. The tank would not be connected to the fuel system of the truck, but would be used to refuel other equipment in the field. There is a GN hitch on the flat bed too and the truck is a crew cab. I can't decide if I want to go with a standard rectangular shaped tank (that basically sits on it's edge) mounted on the forward end of the bed and then a tool box mounted separately just aft of the tank, or an 'L' shaped tank with a tool box that mounts on top the lower section of the 'L' tank. I'd like to get a 100 gallon (or close to it) tank. What are the pro's & con's of the combination 'L' shaped tank & tool box versus the stand alone tank & tool box mounted separately? I know I don't want anything sitting too close to the GN hitch area and I don't think the height of the tank will be a concern since the truck is a crew cab and I won't be able to see the GN hitch anyway. What are some brands of tanks and tool boxes that I should be looking at? I'm aware of TransferFlow, Delta, RDS and Weatherguard. Any others? What's the story on what Transferflow says about new DOT regulations stating that the fuel transfer pump and nozzle cannot be sitting any higher than the hightest portion of the tank? Am I going to get busted if I install a new or used tank that has the pump & nozzle sitting above the tank? Are the little tabs that the tank manufacturers put on the tanks actually strong enough to hold a tank full of fuel in place if you get in an accident? Like say a head on collision or a rollover? BTW: I don't like the Aluminum diamond plate tanks and tool boxes. Way to flashy for me, I want a tank & tool box made out of steel. I'd love to see any pictures that people have of tanks and tool boxes mounted on the front end of flat beds if you have them. Thanks!
