Hey Harry. The best option to install a low profile AC system for the bedroom of your Grand Design is with the Advent Air Low Profile RV Air Conditioner System item # ADV45SR in white or item # ADV25SR in black. These 13,500 Btu systems come with everything you need to get up and running.
The Advent Air AC units are only 31" long x 24-15/16" wide x 10-1/8" tall. The included air distribution box has the controls, thermostat, and vents built into it. These kits also include a start capacitor that makes it easier on your RV's electrical system when the compressors initially kick on.
If you have any additional questions, go ahead and click on the box that says Reply to Jerred H and I'll be happy to answer them.
