Question:
Is there an offset flange to use on the Dometic 320 to get enough clearance? If so, how much of an offset does it give? Currently have the 300 and it’s terrible.

Hey Robert,
We don't currently offer an offset flange but you could just use a residential floor flange with an offset from your local hardware store. You'll likely have to cut the floor to accommodate the offset. The current flange could be screwed on like # T05-0782 or # T05-0784 (hopefully), but it could also be glued on like # 3446336347 which would require you to cut the drain and would probably need to pick up a couple more fittings to reroute the pipe.

Hey Robert, did the residential offset flange give you the clearance you needed for the Dometic 320? Knowing how that setup worked could really help others trying to upgrade from the 300.
