Toilet 'riser' is 'sinking'

1980 International twin 25 ft (bathroom at the back of the trailer).

The riser (about 8" high) that the toilet and sink cabinet appear to sit on has sunk a little immediately around the base of the toilet. Before the jokes start I can tell that I do way a little over 1/8 of a ton but I have not sat on it yet!

I would appreciate some information on the construction under the toilet and sink.
What is under the riser?
Is the plastic riser supported by any kind of frame work?
Is the top of the black water tank just under the floor and if the toilet has sunk a little what is happening to the conduit between the toilet and the tank.

"Tanks" for your help

Typing is getting ahead of spelling

On my post I did intend "weigh" ..... not "way". It has been one of those days.

If the construction was the same as it was in the 60's, the tank is mounted from under the floor, and the flange screws through a hole in the plywood. The plywood floor itself supports the toilet, not the tank and flange (or the tank will crack eventually). I could only guess if its sinking into the plywood that the gasket might have leaked and over time softened/rotted the plywood, which would put pressure on the top of the tank, sagging down. A few pictures might help clarify.

It is not the plywood on the floor that is sinking as the base under the toilet is about 8 to 10 inches higher than the floor. It is this plastic base that has sunk. I will try to get a photo. It will be a week or more for that as I am leaving tomorron morning for our annual deer hunt.
