Sounds killer, I have not had the chance to go up that way before. I would have to stick to the tamer trails for now (maybe 3-4 rated max), as I am waiting to get some good LT tires. Got some P-rated terra grapplers on atm, which I bought before I thought I would be using this truck more for exploring.
Thanks for the info on the MTZ's. Just noticed you are a little north of me, maybe sometime we could get together for some crusing around and exploring. Been looking for more excuses to get the tundra out.
