Hello, I plan to install an AC shore powered air conditioner. I want to have it push out from trailer body when we are at t he camping site. I want the opening to be as airtight as possible, and I would really appreciate insights as to the proper dimensions and sealing materials. I plan to have it on some sort of tray with a roller so I can slide it back and forth. Does this sound reasonable? It seems to me when at the campsite trying to use every square foot of interior space is in my best interest and pushing the A/C outside of ther floor space seems reasonable to me. The trailer will be insulated, so attaining a reasonable temperature inside should be relatively efficient.
Thank you for your attention in this matter.
