I do the lift method at home and dump into our outdoor clean out. But a pit toilet is dry waste. I would think unless it is very seldom used it would not be an appropriate type of waste. Taking advantage of park facilities in ways not designed for is misuse. Wouldn’t want to be guilty of that. Not sure how 2 week boondocking folks handle more waste than fits in the black tank. Are the secondary tanks big enough? Where are they stored? I’m guessing they are too heavy to lift when filled.
We used one of those 42(?) gallon blue tanks for a while. Carried it using a spare tire holder that bolts to the underside of the trailer frame. They're too small and you can't tow them far or fast - so unless you have a macerator pump, fill them in your truck bed, and have a lot of patience they're not good for boondocking. We gave ours away to a neighbor at a Thousand Trails site and said good riddance.
We use a macerator pump (Sani-Con Turbo) and 165 gallon custom-made collapsible bladder in our fifth wheel. Pump it into the truck bed and just take the truck to a dump station. Everything is setup with camlock fittings and the hose is permanently attached, so there is never any mess.
We use a composting toilet and combined the grey/black tanks on our TC, for 83 gallons of grey capacity. That's enough to go a couple weeks on.
