Cracker,
You won't be disapointed, it's a totlaty different driving experience. I went from a heavily modified 03' BMW 330 to my current 06' H2 and have never looked back. I have noticed that the money I used to spend on frequent tires for street/track now goes into suspention modification and trail equipment. As for fuel...it uses alot, no amount of tuning will help much.
Ditch the Evo and get the Hummer, you will be happy.
