I wish there was some option to replace RV toilet with a household toilet hooked directly to sewer pipe, bypassing the tank - for those who are always on hookups. Emergency trips to toilet (without black tank) could be dealt with in several different ways.
It seems to me that a typical RV sewer hose would be liable to clog if connected between a standard residential toilet and an RV sewer connection. It generally is neither smooth (like sewer pipes ought to be) nor at the proper angle. I suppose if your RV were connected to the sewer with a permanent pipe rather than a hose it could work...but that's starting to sound more like a mobile home (or at least a park model trailer) than a standard RV.
