From looking at the specs, it looks like I need an extra inch behind the existing throne. I'll have to measure to see if the 320 will fit. All the other dimensions look ok.
I looked and I don't think the 320 will fit in there. I don't have an extra inch in the back where needed. I bought a Bemis round open front seat. I think that will make it more comfortable.
Great solution. My 2008 Classic has the plastic Thetford. I would like to replace it with a china bowl model one of these days. I'll remember this tip incase only the round one fits.
Won't fit in a 27' FB EB.
I had my dealer's installer look into this to replace a 310.
Another owner had the 320 and tried to fit it, needs the extra inch behind the toilet to wall.
