Hi all...time to open another can of worms...we r going to purchase a 2015 2500 denali duramax crew...just don't see the need for 4wd...how abt some non male ego driven opinions on the subject. ..thx....
X2 on the gear reduction comment earlier. I've used 4lo before just for that reason. I've read post here in the past where guys have overheated trannys just getting in their driveways.
