94 Terry Resort 25W water capacities?

[Herseraph]

Does anyone happen to know the capacity of my fresh water tank, my black tank, and my grey tank? We bought this trailer used, it came with the manuals, but nowhere in there does it list the capacities of the tanks. And I've done a lot of googling and haven't found anything either. I'm thinking I might be SOL.

be cautious and do not turn the 110 volt on without water in the heater tank as it will cause the electric element to burn out.

Thanks? Wasn't really relevant to my question, but thanks, I guess?
