My brother just picked up his GMC Denali 3500 SRW, CC/SB with the 6.6 gas. Traveling across parts of Eastern North Dakota, we got 14-15 mpg on flat roads empty. This truck would need quite a tail wind to hit 20 mpg. Very nice pickup though.
Note that the claimed 20mpg was with the cruise set below 60mph.
Considering the 1500's with the same basic motor can get 21-22 mpg. IF some of the same options like 3.42 gears, 10 sp trans, cylinder shutoff were available options, 20 mpg should be doable on a long term level ground. Assuming you are not headed into a 15-20 mph headwind or other known hit to mpg.
My swag is this is not going to happen anytime soon in the over 8400 gvw 8 lug pickups.
