That is the correct fix. When we picked our trailer up, there was a gap between the floor pan of the front compartment and the front wall of the trailer. The floor pan was supported by small Robertson screws along the front edge.
The shop added self drilling/tapping hex head screws (about #12 in size) attaching the floor pan to the aluminum frame that runs across the front of the compartment. Don't know why the factory used such small screws that seemed to be threaded into just the luan on the front wall.
As far as reinforcement, you could bolt angle iron stiffeners under the floor.
When I installed out BAL stabilizer arms, I bolted a 3/16" x 2 1/2" x 2 1/2" angle on the inside of the compartment crosswise along the front edge of the floor pan to stiffen the pan at the center where the stabilizers are attached.
The floor pan is very light (thin) and I'm going to change the location of my tool box or add a stiffener under it as well.
