I dealt with something similar on my 3326. What is on top of the floor here? The tub? So the top of the floor isn’t very accessible, right?
You’re gonna need some help from a welder friend. Cut a steel plate however big can fit to cover the saggy floor. Jack the steel plate to push the floor into place. Measure and cut a few steel triangle buttresses and weld them from to the bottom of the steel plate and side of the frame. Seal with your favorite flavor of sealant. It’s not really fixing the problem but it’s supporting the floor in place like a shelf.
