I plan to add a toolbox to my TT tongue similar to yours any many others but I have few questions that I hope you can help with.
1) Running the 2 GC2 batteries, how long does it take you to charge them using your EU2000, factory converter and factory wiring from the J-box to the inverter?
2) You centered the batteries, I hope to mount mine off center to provide a larger area for storage in the tool box opposed to 2 smaller. Do you think having the dual GC2 batteries off-center will cause much of an issue with respect to unbalancing the tongue weight?
3) Have you seen any issue with where to "U-bolt" enter the relatively thing gauge steel of the tool box? I had thought of lining the bottom of the box with a thin sheet of plywood to help spread the tension from the bolt, but then on the other hand I an concerned about loosing inside available height.
