This is a RV forum. In the context of using the truck for the movement of the RV, how many have actually NEEDED to use 4WD & how often?
What I wish I could have over a 4X4 is a locking diff. All that weight over locked DRW has to make a huge difference over power to one rear wheel & a lightly loaded front wheel.
To the question of needing 4X4 while camping. Once, backing up a muddy hill on a rainy night.
You have a rare truck. Over 90% of Duramax truck were equipped with the Heavy Duty Power Pack option, Duramax, Allison & Eaton locker. Most of those not so equipped were manual transmission trucks.
