We have a 2007 Fleetwood Niagara. The hinge that is connected to the toilet seat LID broke. The seat lid says "Sealand". Anyone else have this happen? Not a hard fix but finding the correct hinge part. I do not have a owners manual for it and not sure it would tell me the model number of the toilet?? Or if anyone knows the model toiletin a 2007 Fleetwood Niagara HW would help. Thanks for any advice/help.
