B-Plus, I forgot your new monicker. How you doing? Does Bobcote's situation result in seeing thru the wall?
Bobcote, dunno how old your unit is, but when I got mine, I bought a decent undercoating(not the kind I used to buy at a discount place, and half of them would hardly work) and sprayed everything I could underneath. I know it's no miracle, but my mind rests a bit easier when I encounter those conditions. We didn't use ours during any of that type of weather this year, but we did our first year out and there were no problems.
