Hi all, I just upgraded from a 2000 NBS Tahoe to a 2004 Suburban Z71. Quite a difference in power and the interior is light years better! Anyhow, I did notice there wasn't a lock/unlock button by the rear hatch. Is that something they did away with all together, or just a suburban thing, or am I stupid and not seeing it? Seemed to be a nice convience on the old one. Though, if that's my only complaint I must be doing good. Also, anyone have a good recommendation for a tire that looks aggressive, but is still good on the road noise? Thanks!
