Question:

Will this fit in the same area as a domestic standard height model 300? Also does this toilet utilize standard toilet seats or do you have to purchase domestic specific seats like the model 300? Thank you.

The Dometic 320 Full-Timer RV Toilet # DOM27FR requires an 11" rough-in, whereas the 300-series only needs 8-1/2". You'll want to measure to see if you have enough space from the center of the drain (you can also measure from the flange bolts if the toilet is still in place) back to the wall behind the toilet. The seat would also require Dometic specific toilet seats, like part # DMC34FR, instead of standard ones you could find at a local hardware store.
