The 6.2L is a GREAT hot rod ‘car’ engine...but it is currently NOT offered by GM in any +8k GVWR Class TV. Am referring to the aluminum block...or is there an iron block coming ?
You are about to drop down in TV class...GVWR by about 1,xxx.... 2,000 lbs...or more
Check out the RGAWR between what you have now vs any of the GM full sized half ton TV’s. With a PIN of 1,410 lbs...most half ton’s will run out of RGAWR....especially if you will be loading close to the payload rating
Nothing wrong with either the Aluminum 6.2L or half ton’s...just know that you are down sizing TV...and hope your trailer is within that new TV’s ratings
