Thanks, Daox! I've added a picture of the truck and trailer to the first post. The big rectangle on the back half of the trailer is the slide out. Its about 12' long and slides out about 3', really opens up the living area/kitchen. Here's a quick video I made of the interior of the trailer when we bought it. Many changes have been made in the arrangement and addition/removal of furniture since then.
I've still been slacking with doing mods. Only changes I've made since my first post are putting Reflectix in the other windows of the slide and changing all the commonly used 12v lights to LEDs. The LEDs are a huge power saver/heat reducer, wish I had purchased them from the start.
