Spongy floors in passport RL

[Jpmikesell]

I had an issue like others of spongy floors in my passport 2011. I discovered the slide out had 3/4 inch clearance above the floor so cut pieces of 1/2 inch Baltic birch plywood, 9 layers thick, and finished with floor varnish. This solved the spongyness. I did not do under table, floor ok there. Also left ok floor in bathroom. Plywood comes in 5’ by 5’ sheets with excellent finish both sides. Cost about $150.
