1973 Boler - Clean/Grey Water System

[Amis]

HI Team!
I have just purchased a lil run down Boler and trying to do as much research as possible to make a plan to get her up and running.

The water system is throwing me for a bit of a loop.
I cannot find how it was set up in older Boler's online.
There was no tank in the Boler at time of purchase.
I found the clean water hose that was cut, in the storage under the seat at the kitchen table and one black hose under the sink.
Where would the grey water go?
How did they fit a bladder through such a small opening?

Help!
Thank you

I have a '77 17' Boler. There is in the documents section the manual for Bolers and that may help a bit. In my Boler, there are two lines to get water in - one with a female end for city water (filling under pressure) and a check valve to stop water when full. The other filling line is a direct line into the tank and you just shove a hose in and run til it all backs up - then you know you're full. There is a black water tank (for the toilet) and a grey water tank ( for the shower and the sink) underneath. There are black PVC plastic running into them from the drains. There are replacement water bladders at RV stores that can be attached underneath.( mine has a lip that slides over the frame at one end and then has a holding bar attached and bolted down at the other end.
There is a drain cock to the tank as well for draining after winter storage chemicals are used. This may be of help, or else way too much information!!
