Need some advice and guidance for efficiently cooling our 94 Adventurer

[Kevin D Pem]

Well in theory it's a great idea, but as far as placement it seems based on my search mini splits are easier to place on a Class B than a Class A, so far I have read how difficult it is to place a mini split in a class A and have yet to find a video that shows a successful install. The portable option starts to look more likely except the vent will have to go somewhere maybe through the floor?

Portable? You mean vented? Very inefficient!!!
