2014 5.3L Silverado High Country

I have my eye on a 2014 Chevy Silverado 1500 High Country with 113,000 miles, listed for $22,000. Any thoughts on this? It has the 5.3L. I would be going from a 2011 to this. My 2011 is an extended cab LT with 95,000 miles on it; haven't had issues other than wheel bearings and spark plugs. I just really want a crew cab and leather. Service history looks decent. What do you think?
