I still have the frame and tank off of the M49 I am parting out. The PTO for that was mounted on top of the transfer case. If there was an unright gas engine mounted on a flat plate on the frame it could be connected to the PTO shaft that ran the pump (that is mounted at the rear of the tanker).
As far as running a front winch with an aux engine you would have to mount it on the bumper and it would be in the way for a lot of reasons. Cobbling a drive system might be an issue too.
The M35A3's used a hydrolically driven winch that worked off a PTO pump......that is prob the best way to run one if you don't want mechanical linkage.
If you want it mounted on the rear hydo is prob the way to go too.
The pipeline dueces had a winch mounted on the rear behind the cab but finding all the parts and linkage would be difficult and pricey.
Just my two coppers worth.
