Bathroom floor flex help!

I am restoring a 1970 International that I am needing some suggestion on the bathroom which is at the rear. I have flex in the plywood floor when standing at the sink and when flexed can see light from outside. I have done the check for rear end sag problem and the frame only drops about 1/4 on an inch with me on the bumper. I weigh 250 lbs. The 3/4" plywood has definity been wet but is not rotted or punky. The flex area is only about 1" in diameter and sits on top of the holding tank. Since it is not rotted, a way to stiffen seems in order but how??? Any thoughts would be appreciated! Ric

The flex area is only one inch? Whatta ya on? a pogo stick? :-)

Maybe you could just add an underlayment and go camping.

Eastern South Dakota is very pretty with hills, rivers, and trees.

Thanks for the "curt' reply. I thought this site was to help fellow Airstream owners. The area of concern is appx 1 foot in diameter. Anyone else have a suggestion that might help?

Sounds to me that you have some rotted wood under the carpet A quick fix so you can use it for this summer might be that that you can open it up and get yourself a piece of alumnnum sheet (14 gauge) to cover the area Even larger than the soft area then use the camper this summer and fix it properally in the fall

Had the same issue. Look in the rear hatch and you'll see the floor in that area is supported in part by a L lip where the sink base meets the floor. That may have a few screws in it and ours had come out or cracked the L. I used several pieces of straight flat brace (similar to the link) across the L and into the flooring. That corrected the problem.
