Dual 6-volt battery box for TC wheel well

I have not used 6 vt batteries so have never tried that. But I have carried 2 - 12 vt in Boat boxes ahead of wheel well in truck bed for years. Access through the floor level door. There is plenty of room for standard boat box in mine. Made platform to get above curve of bed and spacer blocks to keep them from sliding around. Generally load them before the TC.

I started using 12 vt batteries so I could just rotate them out of the boat every couple of years so I always have fresh starting batteries in the boat. Kind of hard to jump start the boat out on the water! :)
