I have a 2003 Montana Extended version with trailing package (including engine oil cooler, HD Alternator etc), dual climate control etc...
It handles surprising well though the 3.4 Liter engine is gutless, but thrifty on gas. Don't forget it'* a W-Body platform.
I only have one real complaint, the steering is too stiff (trying to give it a sporty feel), the one-centre tracking is too stiff over long drives.
All in all it'* pretty good, it has 27,000 Kms on it (bought it new) but it has to be worth a small fraction of what it cost (~35K Cdn).
