Will be mounting a winch on our flatbed trailer.<br />Trailer will have 2 6volt batteries onboard.<br /><br />We want to hookup the charge circuit from the truck to the trailer, but when we go to use a winch, we don't want that much current draw going from the tow vehicle small 10gauge wire.<br /><br />I don't want to take the chance of having to always remember to unplug the cable before using the winch. I own the trailer with 3 of my brothers, and the same person will not always be using it.<br /><br />Thoughts?
