Last night, I dug into that damage. It is just awful. Below is a pic of a portion of the rotten material, after I removed most of it. What you see in the forward part of the pic below, is the outer layer of laminate. There is only 1/16" of laminate between us and the outside!
This same service adviser said that repairs would likely cost over $2,000 !! Luckily, I think that I will be able to repair it myself. I used to be a cabinet maker you know, working mostly with laminated cabinets. Below is a pic of the material purchased to do the repairs. It costs only $60.
At least we will be able to work here at Wild Turkey Camp in peace and solitude. Coincidentally, just as I typed the word "solitude", the first vehicle that I've seen on this mountain drove by. About five minutes later, it returned and went down the mountain.
