Keystone Cougar vs. Heartland Wilderness (Quality)

We had a new 2006 Cougar 243RKS and loved it. It was very open and light due to the number of windows. We did have some initial teething issues that were fixed under warranty. I found that Keystone stood behind their products very well. Unfortunately our selling dealer couldn't repair anything despite numerous attempts. The quality was very good and after a few years of problems we had many happy years of camping in our trailer. I have no idea about Wilderness quality.
