The one I buy is a laundry product and I always find it in the laundry aisle. I pay ~$9.00 for 32 oz.

I have never heard of this method, We have been living in our rig full time since March. The wife is returning home for a few weeks. I think im going to try this while its just me.

The TROUBLE with leaving black water in the BLACK water tank is that while traveling down the road the sloshing liquid dissolves the tissue paper and forces it past the Black Water Flush Nozzle. The next time you try the Black Water Flush it will not work because there is now a paper mache plug stuck in the Black Water Flush Nozzle.
The FIX is to drain and rinse the tank, drop the belly liner, remove the nozzle that is located incorrectly at the bottom of the tank, dig out the clog and you are back in business. Doing this one time was enough for me.
While working on the flush system you might want to think about relocating the check valve and back-flow preventer from inside your living space to somewhere on the basement ceiling. If and when the back-flow prevented leaks it is better to have a wet basement than a wet living area.
While you have the belly liner down you might want to remove the construction debris and wrap any electrical wiring bundles that are chaffing on the metal cross members.
