If the wife and I just "contributed" to the black tank for two days and I thought I had to dump it, I would use the black tank flush feature to make the process more effective. Normally, we dump after its 1/2 to 2/3 full to get a good evacuation.
If I didn't have a black tank flush, I would wait until the end of the second weekend. We just went six days before dumping and there was no smell emanating from the tank, which confirms previously expressed opinion that my poop doesn't stink. YMMV...
