On a stock 800, if you have good knobbies just air down to 5psi and run in 4wd. Can do 90% of the stuff at Glamis like that if you know how to drive in the sand (momentum is your friend). Big hills like China Wall are not doable, but you won't be able to do them with a stock 800 with paddles either. If you just have to have paddles, probably something like a Skat 6-paddle for a stock engine would be best. Too much weight and not enough horses to pull much more than that. Smoothies on the front can help with speed, and actually do help pull some in 4wd. I personally would spend my money somewhere else on a stocker.
