I'm still dithering on a new truck for my daughter. An SLT/LTZ 1500 with max trailer, 8 speed (8L90E) and 3.42 gears costs about the same as a 2500/3500 similarly equipped with the 6.0L and 6L90E 6 speed & 4.10 gears. Because of the terrain, either going uphill or downhill, cylinder deactivation in the 6.2 & 5.3L engines may not improve fuel economy. The speed limit on her 45 mile each way commute is between 80-100km or 50-62 mph in the old money. She may never see 8th with the 8 speed, or 6th with a 6 speed & 3.42 gears. The 1500 chev LT with leather, ( wet dogs and drooling babies... can't get a SLE 1500 leather anymore) 5.3L max trailer & 3.73 gears is an option and $8K cheaper than the 6.0L HD, or about $80/month less payment. Because of sharp rocks on the highway, the HDs already have the tires we need, so that saves a few bucks right out of the gate, and the serviceable suspension and steering components should last longer. There are only 2 locations to grease a 1500 and about 10 on the HDs. Average use is 2-4k km/month or 1,500-2,500 miles. Will the HD truck kill us with poor fuel economy, or be about the same as the 1500? Any more than a 10% increase in fuel cost will kill the HD option.
