Power wash mystery leftovers

Today we had our 42 rdb power washed because it had been dust bombed so badly here in Northern California that it really needed more than a simple waterless wash. While the wash company was drying the rig, I stepped inside to look for water leaks. Fortunately, I didn’t find any puddles but I did discover some mysterious stuff on the TV console and on top of the top of the valance. I’ll let the pictures speak for themselves.




Any ideas what this might be? Ryan, I’m guessing you probably know exactly what this is.

Looks to be the wall styrofoam insulation.

I agree with ERamsey. Looks like styrofoam to me.

Front cap sealant… needs caulk… etc… side panel my have a water leak by the rain gutter etc… or by an awning attachment fitting…
