The repairs are easy if you have basic tools, a place to work on it off and on for about 2-3 weeks.

....trailer frame. The open spaces in the aluminum frame is filled with styrofoam for insulation. On top of that is 2 sheets of 2.5 mm thick Luan plywood that are attached to the frame and glued together. Usually, vinyl flooring is glued on top of the Luan to finish the floor.
The problem is when water leaks in between the vinyl flooring and you are unable to dry it out, it rots the Luan plywood.
After removing everything I could from inside my trailer (excluding cabinets) I was able to see the water damage.
Next, I carefully removed the damaged wood flooring and cleaned the areas with a mix of bleach and water. Wear rubber gloves and use a scrub brush. Apply a thin coat of 2 part marine epoxy to seal where you removed the Luan and around the area. 2 part Marine epoxy is about $150 a gallon and found at most boat shops.
Go to Home Depot where they sell Luan plywood which is 5.0 mm thick.
Carefully cut and fill in the areas you cut out in your floor. You will either glue and/or screw the replacement wood in place. Cover the wood and surrounding areas with a thin coat of marine epoxy.
Now you can sand smooth ready for new vinyl flooring.
What I did was add another layer of Luan plywood on top of my entire trailer floor and sealed all the joints, cracks and corners with high quality silicone sealer. Next came carpet padding and indoor/outdoor carpet using staples (same method the manufacturer uses to lay carpet in trailers.
We are very happy with the results, the cost was significantly lower than having an RV shop do it and the trailer was not tied for months.
