When traveling, I dump each morning before leaving the CG or every time there is an opportunity. Like Randy mentioned, I fill the black tank nearly full before dumping also and do a bottom rinse.

Bottom rinse(aka back flushing) goes something like this; after dumping blk. tank, 1. leave the blk tank valve open, 2. raise the dump hose up a couple of feet above the dump outlet with your right arm, 3. with your left hand, open the grey valve and let a good bit of water into the blk. tank...........assuming your have grey water, 4. close the grey valve, 5. let hose down to drain blk. tank. Repeat as needed.

After a trip, dump the tanks, fill the black tank up to the toilet inlet, eyeballing thru the toilet, with soapy water. I use dish detergent or whatever is on hand, though nothing with bleach in it. I let it soak for a few days then dump and rinse a couple of times. Seems to keep things working fine.
