Thanks for the comments. I have two main concerns:
1. The roof weight in the middle of the "unsupported" wall where the full wall slide is. At least going down the road the slide is in and may add some stability/strength.
2. The power issue already mentioned above. I had a separate power feed to my second AC on my 5th wheel but it was prewired to the breaker box. I would not be opposed to a separate power supply if is didn't look jerry-rigged. I could possibly run conduit long the roof to the back over the closet and tap into the old dryer circuit. I removed the w/d for more storage room.
