Im still convinced that the best place to mount a charger is in the back of youre truck, with clips on the leads, and lay it on the deck when charging ! Alot of weight eliminated from the boat, the beating it has to endure in the bilge, and ventilation issues all wear on the life of the charger. When mine goes south i will not remount one, but do as my friend Ward, and carry it in the truck when necessary.
