Toilet Keeps Clogging: Macerating Toilet Effective Solution?

We have Tecma macerating toilets in our 5th wheel. We like them, they work very well. They also eliminate the possibility of a pyramid in your black tank. If you like to boondock a lot they might not be practical. With just 2 of us, I need to dump the 50 gallon black tank every 4-5 days.
