I've got a 93 Pajero which is set up identically to an SR except for a diesel engine... I've done Moab trails twice now... open diffs front and rear, 33x10.50 bfg mt's, but rock sliders...I've done KaneCreek, Metal Masher, Hells Revenge, Steel Bender, fins 'n things, and a bunch of others, over the course of two different weeks, two different years. I didn't need winching with the exception of the end of Kane when I blew through two sidewalls simultaneously! No broken axles...
Moab is a lot of fun in a mostly stock montero-pajero!
