Re: 12v Winches... Good or Bad?
We use power winches all the time b/c we never dunk our axles. it's an investment against bearing and other repairs. But be sure to have the crank in case something goes wrong in the wiring.
Get your wiring hard wired to the vehicle, unless you use several vehicles If you don't hard wire, use the proper guage wire from start to finish and get good clamps. If you do hardwire, leave plenty of spare to reach the trailer post; you may find yourself pulling a different trailer and it won't reach or if you leave it plugged in at the ramp, you need the extra when you turn.
Good for you for encouraging your wife and her friends to use the boat. If nothing else, she will, in turn, encourage you. I've never understood the people around here who keep their wives out of the boating process. Maybe it's because where I live and grew up, all my life and now, there are lots of female boaters who are damn good at it. In factr my mother, who grew up on the river, was better at it than my dad, who grew up in the mountains and city--though she didn't let him know it!
