4wd steep grades

what is the steepest grade you guys have taken the tacoma out on? on a narrow 4wd drive road I came across a big hill. about 25 degrees average. the steepest parts was about 30 degrees and the uphill climb is about maybe a bit more then a mile.

i was about to throw it in 4lo when i noticed other trucks and jeeps parked at the bottom and decided i should probably do the same.

 

It really depends on how much traction is available. Moab Utah has slickrock terrain, its like sand paper, you could drive a honda civic up a 45* climb there. It also depends on if it's the kind of climb that will allow you to maintain momentum; if there is a turn or a step you'll have to slow to negotiate it and you'll have to depend on traction and no momentum. Likewise, a taco on a sand dune without any momentum isn't getting up a 15* climb.

Back to traction: a V6 Taco in 4lo1 could climb a wall if there was enough traction. It'd be pretty tough to flip a taco over vertically, BUT if you bounce it and get sideways it will roll if too steep. I've side-hilled some stuff at about 30* no problem.

 

I don't know how steep they were, but i've had my rear end get pretty light going down a few hills. One was a little off camber and when my driver's front tire dropped off a 6" high rock ledge, the passenger rear(most uphill tire) lifted off the ground for a second. It was about as sketchy as I'd ever like to get.
