Come on George, I cannot count the number of times you bad mouthed AWD a couple years ago. I know you like to stay in the "different" club though so it works. Don't use a transfer case out of a Denali like mine, you want the viscous type out of a Sierra Denali or SSS...or like George said, a 4WD unit that stays in 4WD....along with an AWD (no actuator) front axle. I'd probably try to find a manual shift transfer case just in case I wanted 2WD, I could crawl under and move the lever. You'd have the benefit of 4LO too if you wanted to move a building or something. Something more odd that might suit someone's needs is an RPO NR5? T/C that is full time 4WD but has a 4LO option (electric shift but one could build a 14mm lever to use underneath)....they were used for about three years in Tahoes (saw my first one this week, 2004 with 233K miles).....possibly longer in H2's, etc.
