i have a funny feeling that the clam adapter plate must end up costing you guys a few holes on each battery. which makes some sense i guess. mine hasn't even left the truck so it sits out in the cold all of the time and i know i've got 25 holes for sure out of it. this is devils lake. i haven't measured the ice yet. but, i am guessing its at least 24 inches.
That was my thought too. The gear box add on has 2:1 gear and double the torque. I had a clam plate without the gear box. Sold it off, I might be interested again if the gear box is legit. Otherwise, just more added weight to lug around.
