Amen to the black tank flusher. Mine is a No-Fuss Flush system that Jayco installed, and I sure wish there had been one on my last TT. The only thing that has ever gone wrong with the system is a bad vacuum breaker valve, and, once replaced, it really makes flushing easy. Will never be without one again, if I have to install it myself.
