Black tank- dump it or leave it?
Our TT usually stays on a permanent site, which we visit every other weekend or every 3rd weekend. When we depart on Sundays, I usually fill the black tank up with water, since it's nowhere near be...

Letting a black tank sit does not generate odor in the rig if the vents are working properly. If there is plenty of water, solids do break down extensively.
As said many times - the key is plenty of water in the black tank at all times.
I would tend to agree with this. So long as your black tank vent works properly and your toilet drain seal works properly, you shouldn't have a problem. Leaving your toilet lid down will help reduce any evaporation issues. The longer your solids sit in water, the more water they absorb and the softer it becomes. Look at dog poop out in the rain... it absorbs water, expands and becomes very soft. That's why I try to clean out my dog's yard BEFORE it rains.
OP, if you want to go this route, I would throw one of those black tank chem packs down just before you leave. that will help break stuff down while you are gone.
And again... water is your friend. You should NEVER leave the bottom of the tank dry... EVER. Dry black tanks, or insufficient water are what cause the dreaded pyramid.
Then again, as long as you are properly draining and flushing out your black tank, there is no need for this and you should just drain your black tank before you leave and add a couple gallons of fresh water back in.
