Great to hear it tows well with the 7k lbs. I was stalking on another forum and I think the holding gears is also a transmission tune that GM does on HD trucks vs the 1500 chassis. The 1/2ton will always try to shoot to the highest gear (even in tow haul) vs the HD tune which will more willingly hold the gear.Installed a Tekonsha P3 trailer brake controller this morning, and went to pick up the camper this afternoon. The 4.10 gears are perfect for holding 5th on the highway up and down modest rolling hills - exactly what I was hoping for. Essentially zero squat (1/4” or so) from the 750 lb tongue weight.
Throttle response is more restrained, requiring much more pressure on the pedal than the GMT900 Yukon XL Denalis for the same result, but when I do give it the boot, the 6.0 holds its own with the 6.2’s quite well.
1/4in with 750lbs… thats nothing!
