I've begun looking to replace my Trailblazer and am interested in the half ton crew cab pick ups, I know the 5.3 is a decent motor in these trucks minus the D.O.D. however I'm coming across a lot of used ones with the 4.8l, so far online reviews say its a decent motor that powers the truck well with the takeaway being loss of towing. Now I'm not in need of a tow rig, just would like more room and a pick up bed for my weekend warrior trips to Home Depot, Curious to see who here owns half ton chevy's with either of these motors and get their ideas as which they prefer and why?
