We just bought a 20BHLE last week from a dealer in Omaha, NE and towed it back to Colorado. Haven't camped in it yet and the camping season is pretty much done here. I just winterized it yesterday. Can't wait for the spring to start taking our 3 years (will be 4 in March) twins out camping.
We have a 2010 Suburban 1500. It does not have the HD Tow Package but I added a transmission cooler and brake controller. It towed the camper back from Omaha no problem. We did add a WD/Sway control hitch.
