Black tank blues
I'm rehabbing a '76 Ambassdor. I got the inside gutted, mostly got the inner skin out, and once the endcaps are out and the floor gone, I can check on the tanks. Except I think I know what kind of shape the black tank is in... Back when I was gutting the interiors, I pulled the toilet and saw a neat, decomposed mound of waste sitting directly under the toilet. It was odorless, not that I took a big whiff off anything, but from what the PO told me earlier, I'm guessing it's his grandad's err... remains. He apparently lived in an ocean front RV park until he passed and willed the AS to the (briefly) PO. Perhaps during his last few weeks, he didn't quite make it to dump station.
So I'm assuming I have a dried out, caked on pile of waste in the black tank. I'm not squeamish. I will go elbow deep(with gloves!) if I have to. But I'd rather work smart than work dirty. What's my best option? Right now, I'm considering filling the black tank with water and an entire jug of bleach and driving an hour on some bumpy country road.
