Some Unimogs have centre mounted winches, they route the wire thru ali pipes along the chassis.
If centre mounted i would go for a pto, as I have seen some truly magnifizent creations on Mogs.
Lets say a 45deg slope, Defenders and Yotas are struggling up it with their pimped 8274, flying past, and I mean literally flying, comes a Hellgeth Mog with a PTO driven Rotzler. Ironic bit is that ther are 4 G-Wagens dangling from its towhitch as well...
I just watched it gobsmacked, shame the winch weights half wot a Defi weights...
