Our previous unit's Thetford Lasted 15 years without any problem, but we only full time 3 years.
Now full timing for 3 years with a unit with a Dometic 210 in our new unit I changed the seal twice and ready to install the 3rd. I bought 3 seals the last time at a great price, so still have 2 spares. Its to find where I stored them Ha ha ha.
