Thanks for the compliments guy - I still need to scrub the 3rd row seats, and I have absolutely no desire to after all this.
Sask, search was (mostly) limited to Escalades. If it were me I probably would've gone Tahoe Z71 for the manual 2wd/4wd setting instead of the AWD in the Slade. Like I said though, Mrs.Firm had always wanted one of these, so I figured this was a good time to make her happy with little sacrifice on my part.
On the carpets I used Mr.Clean mixed with warm water and a scrub brush. On tough spots I would soak the spot in straight Mr.Clean first, then scrub. If that didn't work I'd soak the spot in Resolve carpet cleaner, then scrub some more. There's actually a couple spots I couldn't get out entirely, but I've got some industrial strength carpet cleaner in the basement that I am going to try when I get a chance - my focus last weekend was to get the dirt/smell out of it.
