Update by user Sep 17, 2020 Had to get the original dealer involved back in Ohio, I live in AZ. Dealer dealt with the warranty. I did not want to put the original cheap toilet back in and since dometic will not deal with the end user had to pay full price for two porcelain toilets and the dealer agreed to sell the new warranty toilets at their cost and eventually send me the money. So basically screwed. New toilets in waiting for dealer to send a few bucks, but not holding my breath. By the way heard nothing from dometic. When as a company you stop doing what made you a good company and brought you success you are heading downhill. Original review posted by user Aug 17, 2020 Bad dometic 300 toilet smells of urine. Was told warranty does not cover bad smells and that they will not deal with the end user. Warranty will be handled if I pay a repair shop to trouble shoot and evaluate the problem and contact dometic for warranty. Urine is collecting in toilet and stinking up my new 2020 RV. Why should this cost me a dime? Also I wanted to upgrade to a better toilet a 310. They informed me they dont upgrade. User's recommendation: If your unit comes with dometic 300 toilets upgrade to 310 or 320. Or different brand.
