You guys are going to love Mission Impossible, been there 3 times now. Just a little info: MI is doable with 31's we had an old Bronco run with us with a 2" lift 31's and open front and rear. We did have to drag him around a few places and he had to take a few bypasses but he had fun. MI is what you make of it, Ask Pat what happens when you ask if there is anything a little harder.:rof: The biggest thing I can say is make sure your brakes are good and tight, there are a couple of hills 1 real long and kinda steep and 1 real short and you will swear the rear end will come over before you can get to the bottom which by the way has a 90 degree turn with little to no run off area.
Like Pat said there is alot of river crossing but nothing to deep. Ill finish with this, take a camera because the scenery is great!!
Any questions feel free to ask. Digger
