Yep join the leaking toilet club
,I did the same thing and replaced with a Dometic 310,and like you 1 broken dining room chair cushion from kneeling on it too hard(don't do that gang)replaced on warranty ,other than that it has been trouble free for me in the first 4 months of ownership and me and my wife are really happy with the 2015 and we had great luck with our 2012 as well
,seems like yours are pretty minor (SO FAR) ENJOY FLORIDA you dirty dog while I'm up here in the Rain ,cold and WIND(60MPH Gusts) on the WA State Coast
