To find the correct replacement flange for your trailer you'll first need to remove your current flange to see exactly how it was attached. Your current flange could be screwed onto the pipe or glued to it so you'll need to find out which style you currently have and find the matching style.
If your flange is glued to the pipe then you would need to cut it off and will most likely just have a 3" pipe sticking up to connect to. In this scenario you would use part # 344633633, which has a hub end that can slip over the pipe and glue it with some abs cement # 3447530889.
If you need to add a bit more pipe to get up to the right height then you can use a 3" coupling hub like # D50-2935 and some straight pipe. If you choose to install another one at the top you could then use part # 3446336347, which has a spigot end and will slip inside the hub like straight pipe would.
If you lucked out and have a screw-in flange then you'll simply need to choose the # T05-0784 if the threads are on the outside of the pipe or part # 3446336343 if the threads are on the inside of the pipe.
Once you have the flange connected to the drain pipe you can then shoot some screws into the top of the flange to secure it to the floor. Your Dometic 310 # DOM57FR should have a gasket on the bottom of it already, but if it's worn you can use part # DOM28FR as a replacement.
