Now the good part - the Dometic 310 actually sits closer to the back wall and gives you more leg room on or off the throne. Having porcelain with rim cleaning holes is very good. The Dometic lid is a 'soft drop' and is removable making the bidet install possible in the first place. For anyone who has not used a residential bidet - once you doo (pun) you will want one for your motorcoach or travel trailer.
Filling up the bowl while using the bidet would be next to impossible unless you are spending a lot of time in the wash process. The bowl is huge. The bidet adds negligible water to the bowl level. What it does do is lower the amount of expensive RV tissue you will use and then drop into the black tank. Without tissue you don't have clogs and the need for harsh chemicals.
Oh I wasnt expecting plug & play. I just installed a shutoff valve and a 20" flex hose when I replaced the thetford water valve. I assume at most the floor flange would also need to be replaced, but again, shouldn't be that bog of a deal.
