Help: Size of wastewater tank?!!!

Hello, is there anyone out there that has information on the standard size of a waste/black water tank for a 1967 airstream caravel? I don't have a owner's manual and the only other option is to take the belly pan off. I've tried to research the internet and found nothing. The fresh water tank looks to be 20-23 gallon tank. It is imperative that I get this info soon. I would greatly appreciate if anyone could shed some light on this area in question.
Best regards.

Fallon there is a simple way to find out. Start with an empty tank and add water one gallon at a time until full. Keep a count of the number of gallons added and there you have it, the capacity. Easy-peasy.

The tank on an Overlander is going to be much bigger than a Caravel. I would say it's more apt to be in the 8-10 gallon range. Our '64 GT is 10...

Have you looked through some of the documents here for any clues? Your best bet is to use a gallon milk jug and your fingers...
