Dometic 320

Has anyone installed the Dometic 320 in the FR Vibe 221RBS? If so, any problems with the install and were any additional parts required?

might save a changeout

why are you changing out? a leak? just like porcelin bowl ?
if you have a leak, the new water valves that are activated when you stand on flush pedal....are a must to get....originals were crap [no pun !!] redesigned ones that fit 300/310/320 dometics are a snap to replace...bought mine on ebay $27 i9ncluding shipping.

Should have no issues swapping out. The measurement from center line of toilet opening to back wall is probably the only issue just like it would be for home toilet swap out. The flange mounting that exists should be sufficient and mounting stud orientation should be the same (comes with hardware for mounting). The water connection may require some modifying but nothing major. The Dometic internet site has the install info (required dimensions) available for viewing and/or download. The 320 flush will be the gravity type (elongated) unlike the model 310 pressure swirl (has a round bowl) I believe. Could be wrong.

I installed the 320 in our Vibe 221RBS, an exact fit with no plumbing mods. Really nice toilet!
Thanks for the reply!
