With his description he doesn't want a 2 1/2 ton,he wants a newest model 5 ton that's easy to work on with a winch.
Since the MTV's have lots of electrical problems , problems with cab hydraulics, and driveshaft vibration problems that break engine components and now it seems several members have experienced motor failure from oil lines rubbing , i would say they are out. So that is the reason I suggested a M925 , newest 5 ton with winch , automatic transmission and full air brakes that is fairly easy to work on . But your right SW the M54 or 809 series, with manual transmission, air/over hydraulic single circut brakes and a sprag transfer case may suit his needs . I would say he needs to look at all and compare the good and bad of each .
