My first class C was an 07 28A. It was a pretty good RV, but like most have stated it is "Entry level". I don't regret buying it, because we were unsure how often we would actually use it. Since we use it about 20 times a year, it was worth it for us to move up to one with a little more room and a few more features.
I loved the layout. It was great for 2 people. The TV was in a great location and I like the dinette and couch being on opposite sides of the coach. I also was pretty happy with the Chevy 6.0L. We got about 9-9.5 mpg's when towing our Jeep. I don't know that I would have wanted to try any pull a Jeep in the mountains with it, but for driving around Texas, it was great. We drove it for 5 years, with minimal problems.
We eventually traded ours in on a Sunseeker. One of the best things about the Sunseeker verses the Four Winds was the solid fiberglass roof and fiberglass front cap on the cabover. As you probably know the worst problem you can have is a water leak. We had to replace the rubber roof on our Four winds at $3,000, and we also got a leak at the seam on the front corner of the cabover.
We also got ducted air with an actual thermostat controller.
