Yes, yes, yes and yes :-). It was very easy to do. I chose to glue the cam-loc fitting to the rv's drain port but you could just use a twist adapter. The Drain Master hose seems to be made of really high material. It is pricy but works really well.
It worked out do well that I have changed all the fittings on both my drinking water system (water softener, filters, etc) and tank flush system to cam-loc fittings, no much nicer than the quick house adapters available at home centers.
