First you will need to determine how far your current flange is from the wall on your camper. The Dometic 300 Weekender # DOM64FR requires a rough in of 8-1/2" to install without modifications. With the Dometic 320 Full-Timer RV Toilet # DOM27FR requiring a 11" rough in there are a couple options. You will need to inspect the structure under the floor on your trailer to determine if you will be able to move the flange under the floor or if you will need to create a raised section of the floor. If your black tank is directly under the floor and cannot be moved to the 11" rough in you will need to create a raised section which will allow you to source a toilet flange offset from a local hardware store to install the Dometic 320 series toilet.
