This is one of the most comfortable trucks I've ever owned. It pulls a 7500lb travel trailer with no problems. The only repair I've needed since purchasing it new is the front hub assembly which wasn't difficult to replace. I did replace the OEM hitch because of failures on other GM trucks. This has been a great truck to own and I will buy another when the time comes. I hope they will put a diesel in the Suburban/Yukon XL line.
Seats and ease of driving. Good layout on the controls.
Put a bigger engine than the 6.0 on the future trucks or give a optional diesel.
