If you ever decide to add a winch or two, might try looking in old automotive scrap yards. Not sure what it's like in your area, but within 50 miles of me are 4 or 5. I know from looking some have old wreckers, tow trucks, etc that have the old PTO drive winches on them. Would probably take a bit of work to remove and rebuild them, but may be an option. Just a thought.
