Expert Reply:

The Dometic 320 Full-Timer RV Toilet, # DOM27FR is not a direct replacement to your current model. To install the Dometic RV toilet # DOM27FR you'll need the Valterra RV Toilet Floor Gasket with Hold Down Bolts # Q23653VP and either the RV Toilet Floor Flange # T05-0784, which has 3" diameter female pipe threads OR RV Toilet Floor Flange # T05-0782, which has 3" diameter male pipe threads.

There's one measurement you should double check to see if this toilet will easily fit into your bathroom. The rough-in measurement is the minimum distance you'll need from the wall to the center of the flange on which the toilet will sit. To measure this distance without uninstalling your current toilet, the mounting bolts on the side will typically tell you where the center of the flange is. You may want to triple check if your toilet has an offset flange or 4-bolt mounting style.

The Dometic 320 Series RV toilet has a rough-in measurement of 11". If your rough-in measurement is less than 11", select a toilet model with a lower requirement or consider alterations to make it fit. Keep in mind the overall dimensions of the toilet, and measure for yourself to pick the best model for an easy DIY upgrade.
