I want to do the Alpine loop from Silverton in Mid September. We will be driving up to CO in my wife's '98 Land Cruiser. I have read that sections require high clearance and short wheelbase. The Toyota has low gears and a rear locker, but I'm worried about clearance, about 9" w/ 112" wheelbase. (don't want to bang up her car). Is anyone familar with the loop and can tell me if it is passable / clear at this time of year and do you think the Land Cruiser has sufficient clearence with the longer wheel base?
