It may only be where i happened to poke, but i do not know as of yet. I anyone knows what i am talking about i would appreciate it if someone would chime in and let me know what it is, and if i'm going to need to replace the mystery layer of foam as well as the plywood. Thanks for all the info i'm sure to get, Chad.
On some trailers, there appears to be a layer of insulation under the floor, and a layer of aluminum skin just under that. It is usually in the front of the trailerm centered. It is for when the belly pan is cut open in that location for placement of the spare tire. Not all trailers have it, and I haven't seen the insulation anywhere but in that spot.
