Toilet mounting

i changed toilets several months ago
FUBAR
in this bounder, the floor flange was glued to tank inlet pipe,
and i could not remove it to install a new flange
the bolt pattern was different orientation and i had to use a vibrating multi-tool with plunge saw blade and cut NEW notches in the old flange

this is the 3rd MH, that i replaced the old toilet, and the only one that was a PITA, the other two were easy

I changed out the ceramic one in my Monaco. Took about 30 min at the most. Has worked perfect ever since.

I'll just add that I replaced a toilet in the MH. Looked easy. That is until I took the old one out and put the new one in only to find out that the water lines where not the same height and didn't reach. sigh.

I had to take the new one out and put the old one back in. So check the water line hook up that it matches.

Planning to replace our Thetford toilet with a Dometic 311. From what I can tell, the base mounting bolts are the same. Can any one verify that? Are there any other installation issues I need to be aware of?

Thanks for your help.

Went the other way.. They are

Which thetfrord are you replacing?
Verify bolts are parrallel to back wall, they should be 10 inches from back wall
