It depends on how soon you are going to use the trailer again.  You don't want the tank to dry out with any "solid remains" in it.  You also want enough volume when emptying the tank to wash everything out.  I'd add enough water to at least half fill the tank before dumping.

I dump often, even when switching campgrounds. I figure it is just like sweeping your kitchen floor at home, you just can't do it too often. The cost for half a scoop of Happy Camper treatment isn't prohibitive enough to haul my business with me. And I am camping, so I have all the time in the world. I honestly believe people overthink their black water tanks. I have even heard of folks who are so weirded out by them that they will crap in a plastic shopping bag and toss it in the dumpster so they don't have mess with their toilet. To each is his own I guess, but so unsanitary. So gross.

you don't necessarily have to dump your black tank if there's not much in it, but i usually do at every opportunity. i don't like the idea of body fluids/solids sloshing up the sides of my black tank when driving down the road. i dump at the campground, rinse out the black tank then fill it with a bucket or two of fresh water and rv toilet chemical. keeps everything fresh and sweet smelling while enroute to the next destination and the chemical description states it helps protect the valves from drying out/cracking.

    safe and fun travels....................

On a long trip we usually dump the grey tank more often than the black.  If the black tank is not very full we will add water (sometimes grey water) before driving to the dump station to improve the slosh factor.  We always add water to both tanks after they've been emptied.  And when storing the trailer, our tanks are always empty and clean, even if we are using it again in a week or so.  I guess it would depend on the temperature but neither tank is going to be pleasant to be around after sitting for a month.


We had a Casita visitor who drove for about 500 miles with her bathroom window open because she hadn't emptied the black tank before storing her trailer.  I don't know how long it was stored but she lived in Las Vegas, so it had been hot.  When she stopped by to visit, she had to park on the street because our driveway is unfriendly.  But when she left, I walked her out to her trailer and commented on the open window.  Standing outside but close to her trailer, I could still smell the stink.  I just hope the odor was contained in the bathroom and didn't permeate everything in the trailer.  That's one hard lesson to learn.
