My TCS came to me with the battery up front, probably a misguided attempt at balancing weight distribution. I had serious problems with grounding. Starting was very difficult. There were many feet of heavy 6AWG wiring added to complete the circuits. And finally, the battery was working pretty hard at pounding its way through the fiberglass floor to make a getaway. About 1/4 of its perimeter was cracked through the floor. I had it moved to the stock location when I had the frame replaced (DPO damaged the frame in an accident). Now the electrics work much better. And if I want to, I’ll be able to add a spare tire in the stock location.
