I would love to but I'm stock as they come with the exception of a kick ass phone mount haha. Plus I don't see to many xcursion threads for down here in San Diego Co.
As soon as it cools off a bit (say by November) there will be lots of places in Anza Borrego that you can go to with a stock truck, even if 2WD. I'm sure someone (myself included) will set up something. Or, just ask for some company on the board if you have a date and place in mind and don't want to go alone.
In the meantime, the parking lot where the San Diego Food Truck Thursdays are held is quite stock-friendly. You won't even need 4WD. Third Thursday of the month.
