2003 Yukon Denali 6.0 replaced w/h Sierra 2500 diesel
A huge thank you to all who replied to my thread about the Yukon 6.0 running hot. We discovered that wasn't the only problem. The inside looks great, engine great but has extensive rust underneath. It didn't show up until four years later as it originally came from snow country. We replaced it with a 2007 Sierra 2500 turbo diesel w/h 6.6 engine. Hated to let the Yukon go but that rust couldn't be fixed. Don't think we'll have any problems pulling now! This forum is great and has so many nice campers willing to help. Happy camping!!
