I've got thin foam strips on the floor in the gaps between the raised sheetmetal floor ribs. Above this I've got 3/4" plywood (then will be laying a closed cel foam subfloor and a vinyl floor.)
The 3 Plywood pieces I used maybe had a little bend or bow to them to begin with - and after a week of laying in the van floor (with minimal weight pressing them down) there is still a noticeable spring and squeak to them in a few places.
Each of the 3 pieces is bolted down in 2 spots (using existing tie-down threaded holes).
So:
A - Should I try and glue down the plywood to the floor rib tops, focusing on the springy places? (which glue?)
B- Should I use some self-tapping sheet metal screws (countersink the heads, drill pilot holes through the van floor)
C - Apply more heavy/weighted items to the floor and wait a few weeks to see if things settle?
