I am surprised there has been very little discussion around the hydraulic winches. The mile marker HI12000 is on my to do list, 100% duty cycle and more reliable than any 12 winch. The 12V winches also put a beating on your batteries...no alternater can keep up with the current draw of a 12V winch.
The MM hydraulics are nice with the only two drawbacks being slow line speed ( not so bad ) and they don't work if the vehicle is stalled out or on its lid for those who are worried about such things. Other than that there is a reason you see them on every flatbed wrecker !
