They're cosmetic and convenience improvements mostly. There are more floorplans now than there were back then (only three then I think), plus there's a new "high wall" model, which has a much nicer kitchen area than the regular models. The new tan and black color scheme is very nice looking. The latest models have an operating window in the door and two more bubble windows. The power cord attachment is much better than the way the cord was run in the earlier models. The new models have a digital thermostat that is more accurate than the one in the original models (mine lets it get way below the set temp, then runs the furnace until the temp is way above, seesawing back and forth all night). The furnace fan in my friends' 2014 model seems much quieter than mine. There are pull-out drawers in the cargo compartments on the newer models--you have to reach in and fish for your stuff in the original models. The new models appear to have a larger water pump. The stereos in the older models were almost worthless, the new ones are better and include USB ports. The original models did not have an outside front storage bin or the bike holder/toy hauler options that are available now. That said, I've had three summers and about 20,000 miles of pretty much trouble-free enjoyment with my 2011, so I can't really complain. It's still dry in a storm, warm in a chill, comfy to camp in, and a pleasure to tow. People still slow down or stop when they see it at a campsite. If it's not as pretty as the new ones, well, it was cheaper to buy too. I guess it all evens out. I hope you have fun looking for a used one and even more fun after getting one! P.S. Look at the post thread "First Trip in the New Camper" to see the new color scheme.
When you're looking around, you should know that the Rockwood and Flagstaff brands are identical except for upholstery colors.
It's never too late to have a happy childhood!
