Don't know about the 6.0 GM vs the 6.6L Dmax but my 345hp/365ftlbs '05 Hemi powered 2500HD Ram towed our previous 10,400 lb 5th wheel up the grades faster than our 250hp/460 ftlbs '03 2500HD Ram. With horsepower you can make torque through gear reduction. That extra 100 hp made a pretty big difference at highway speeds.
