2 year update
 the stock tires are only good for southern Cal. I purchase a set of BFG AT and they made a world deference off road. It will climb now with all most no wheel spin, where as before the stock tires just couldn't find traction. The only down side to using real off road tire is I lost about 2 mpg. No real problems with the truck, I even have hauled one cubic yard of gravel with it, just got to go slow.
