Not much difference between the 2012 & 2013.
Take it out camping to see if everything works as expected. Our dealer had a couple of minor things to fix after our 1st time out.
Note that the TV signal boost is a small button with an equally small green light, it runs off the battery so shut it off when not in use. I do dry camp a lot though.
Check the slide motor attached to the wall under the sofa as well. Mine pulled off.
Maybe just search the Rockwood section here for the 2109s. There isn't much to do as it is a pretty good little TT.
