I'd say yes, since the system that Ford started using in '05 can react much faster than the older system. It's actually more of an AWD system than a true 4WD system, so it won't perform as well as a system that actually locks differentials.
well, i took the plunge. found some trails near the house. had a couple of mud holes probably 2' deep or so, she did fine. went through some heavy under growth, even over a mound or two. the mounds are 18" to24" tall, she did good. wish i would had better tires, right now i have kumho solaris, street radials, they did ok, but would have preferred a good set of michelins.
if kumho makes a good trail tire i will get it, the michelin comment not meant as a knock on kumhos these have held up great so far. but for serious trail riding, i do need something besides street radials. :bill:
