Here are some pics from today... Spent another 1.5-2hrs starting the tear out. Here is a view of the left (front of the trailer is to the right) side interior before I started. In the front-most storage area is the electrical supply including (apparently) a battery, inverter and access to a plug that allows for powering off of AC. Also a vent setup so that the battery (perhaps anytime the trailer is plugged in??) can charge and vent fumes safely! I think I'll be keeping that stuff intact but may relocate it or build a new enclosure for it....
