2007 Suburban with 171k miles. I have added Airlift 1000 airbags to the rear and I'm in the process of installing a Trucool 40k transmission cooler.
The "does ok" is I wish I had gotten a 3/4 ton or 1 ton truck if I knew i was going to be towing. I got the Suburban because I wanted a Rolling Lazyboy couch I love the comfort and we didnt plan on getting a camper. Before the airbags the ride was a bit dodgy. Airbags made a huge difference. I also run them at 10Lb's when not towing and it feels better around town. The 5.3 is very under powered for this size trailer. I wish I had a 6.0 6.2 or a diesel.
In the next 2 years I'm going to be upgrading and I'm probably going to get a 1 ton dually because my wife has no plans on slowing down with camping and I want a stable platform for towing.
