Can A Dometic 320 Series RV Toilet Replace A Dometic 300 Series RV Toilet

Question:

I have a 2020 forest river salem 26dbud with a dometic 300. I would like to replace it with a 320. Can you tell me if it will fit or what measurements I need to take to verify compatibility?

You'll want to measure the "rough-in" which is the space from the wall to the center of the toilet flange/mounting bolts. A 300 series will have an 8-1/2" rough-in, whereas the Dometic 320 Full-Timer RV Toilet # DOM87FR has an 11" rough-in. As long as you have enough space you'll be able to install the 320 in place of the 300.
