Replaced the plastic toilet
We bought a new 29MV and were surprised it came with a plastic Thetford toilet. Most everything else was an upgrade from our previous RV.
I searched for a ceramic replacement and found the Dometic 320 as the one I wanted, but the measurements showed the base as 16 inches which would have meant cutting into the wiring channel that runs along the floor behind the toilet. After weeks of debate, we decided to just get it and try to make it work.
Turns out the Dometic measurements are from the front of the base to the wall even though that doesn't come through in the diagram. The actual size of the base was only 10.5 inches so it swapped out in less than 15 minutes. I also had to do a simple change to the pex water supply line, but that was easy too. If I had known the actual base size I would have ordered it weeks earlier.
Just thought if other people have been considering a change to let you know how easy it was.
