jdkirk, you have two grey tanks on the 23TR. I always fill the black tank at least to the 3/4 level before I dump it. Then black, grey and grey. By the time the first grey tank is empty the hose is clean (?), what ever clean in a sewer line is. After the second grey tank I rince it out with clear water and store it in a length of PVC sewer pipe with caps. It stores nicely in the rear storage compartment without leaking.
