GAS 6.6 GM

Just traded an 07 2500HD Chevy with a 130,000 miles for a 2019. Did not want to be one of the first to try out the new 6.6 engine. Been there done that with new design products. Purchased the good old 6.0 gasser and will see if I made the wrong choice or not down the road....so to speak. Hope everyone has/had a nice holiday.
