Thanks guys
Tires have got to go for offroad - I agree! I want to use my Irok's with 17" wheels... and I found that KASCAR is retrofitting the H2 wheels to fit the H1 with CTIS!!! Fingers are crossed, but this may be a perfect way to re-use my H2 offroad tire set-up
I bought the 2-year extended warranty through GMPP. Truck only had 38K miles (10 on the engine #8 cylinder recall) - warranty will take it up to 75K miles. I have good friends in low places that I hope to learn maintenance techniques from... but the warranty will cover the big stuff.
Hope to see you guys out on the trails! Badlands in Indiana is my next event.
