First mod I did. I used:
This track:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 screwed to ceiling every foot. Fits perfectly from one side to the other.
These drapes:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Perfect size floor to ceiling and 2 panels completely cut off the cockpit from the rest of the coach. The are also white on the cockpit side.
These Carriers:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Just sewed them to the edge of the curtain with the supplied elastic; space them about 8" apart.
This mod keeps the AC in the cockpit while traveling, and the AC in the living area while camping. Even with reflective shields in the front windows a lot of heat comes in through the cockpit area while camping.
