2005 GMC Yukon XL

This is a South Dakota truck that wintered in Texas so no rust issues but does have paint flaking. There is a dent in the drivers rear and the usual body wear of a 200k truck. The transfer case was just rebuilt by the Chevy dealer but it has a rough idle and I no not know why. Feel free to come look at it. My wife put in a jump seat where the consul goes we have it and can easily be put back.
