We bought a new Tributary 14' in 2006 and ran it for 6 seasons before selling it to my brother fall of 2012. Boat is still going strong. The only problem we've had was a bad valve which Aire replaced under warranty. We upgraded to a 156D.
During the 6 seasons we used the boat it went on 3x Deso week long trips, 2x Chama, many RHT & WW trips, annual Memorial Day Ark weekends, and countless trips on the Upper C. We used this boat on average 25-30 days/year, trailered or rolled & packed.
Cleaning & maintenance: I've only owned Aire boats so I can't speak to the other brands, but I have never found it difficult. We rinse off the boat if it's dirty after a run. End of season I clean & 303 the boat, and open & rinse the floor. Opening the floor is easy: just use dish soap to lube the zippers and they open right up.
The reason you should consider cleaning the floor is that Aires boat hold water in their floors & fine silt can stay behind: pros & cons of this design have been well documented on this site. Again I've only owned Aire boats but has never been a problem-doubt we would have bought a 2nd Aire if it was.
