14K miles is very low for a 2007 truck; is that the real mileage? I've been watching Craigs list for Chevy trucks for the last few months now, and have seen ads that claimed low miles, but on a new or rebuilt motor, while the rest of the truck had 150K.

There is a 2014 4x4 crew with a 5.3 EcoTec 3/flex fuel with 60K miles for $33K, a 2015 with a 5.3 and 139K miles for $28K, and a 2016 with a 6.0L and 47K miles for $39K. There is also a 2009 4x4 crew cab 1500 that had the 5.3 replaced at 100K miles for $19K.
Most of the trucks I've looked at were way overpriced IMHO, given the high mileage of over 150K. I ended up with a no frills 2004 single cab long bed with a 4.8 and 98K miles for $7200; I've recently seen the exact same year and model with 180K miles and an asking price of $8500.
