External fuel tank mounted in bed - thoughts??

Have been thinking about adding an external fuel tank in the bed so that I can go longer distances and not to worry about stopping for fuel as much. Also, we all know fuel prices go up around tourist destinations. Has anyone got the tank installed? Has it been an issue with weight?

    I doubt you will save enough on fuel cost with an in bed tank to offset the cost of adding one.


    Oh I don't know. You can always stop anywhere and drain your bladder in the TT. Fuel prices can vary greatly from place to place. If you travel enough, and if you have the payload capacity, if might pay its self off after awhile.

    Yes, it can be an issue with weight. You need to see how much the extra fuel and the weight of the tank will impact your payload. If you're already at the limit of your payload (GVWR or RAWR), you probably need to rethink it. If not, it's a great way to extend your range.
