More of the same. After these photos were taken, I screwed down 3/4 inch marine ply. I then hole-sawed a few holes in the deck to allow me to pour some two part foam into the voids. I placed a few empty plastic bottles in the voids forst to save on foam. This worked real well and the floor is as solid as can be. No photos were taken 'casue I got so caught up in the job. This was a job I do not wish to repeat anytime soon! That said, it was manageable and went very well. My advice? Try to avoid looking at the bigger picture and tackle things one little job at a time lest it become overwhelming. DON'T GIVE UP! YOU CAN DO IT!
