there used to be a company that would make these saddle tanks, but I don't think they make them anymore.. Realistically they are really simple with minimal modifications... you would have to change your "fill" point from the RH side of your truck to the back of your truck, as the ones that I have seen wiith these saddle tanks had a filler cap just north and outboard of the tail light assembly near where the marker light is... if you get one custom made you would be set. Since your fill pipe for both the main and aux tanks already ride abve the frame rail, you will just need to change where it goes. You could likey get more fuel in the RH saddle tank then the LH as your feed pipe to the aux tank would need to be near the bumper (as thats where it is currently) whereas the main is in the front so you could likely get a good amount of volume in it....

The other thought would be to modify the bottom of your bed and create that as fuel storage.... you can figure ut volume fairly easily just from raw dimensions..... BUT.... please note.... for crash reasons... there is often a "vapor" zone in every fuel tank so that when the "incompressible" fluid is forced to go somewhere, it can, rather then leaving the tank assembly..... typically they see around 5-10% vapor space in a fuel tank assemly to be "safe"
