Much thanks David.

Good tip using Liquid Nails on the velcro. Hadn't thought of that.
Used that stuff to fix a separating DV exhaust isolator. (as per a tip
from Jake)

I'll opt for the less expensive stuff, but will at least google pier
float material. Optimally I would insulate as thick as possible behind
Dometic fridge while allowing for future install of electric fridge.
