Bought a 2003 Tahoe maybe three years ago, friggin love it, needed something bigger/better to pull the camper which was previously pulled by my wife's Jeep Liberty which we almost blew the tranny going up a steep logging road, and so the time had come to get an 8 banger. But, I'm here now, so yes, its old age is showing, little problems getting bigger, I hope to find some good advice here, which I already have just from what I've read so far. There are many good ppl here which are extremely well versed in Zen and the Art of Motor Vehicle Maintenance. It's truly impressive.
