What size A/C would you buy, and where would you mount it?

I agree.

There should be 4 plugs in the ceiling about 14" apart marking the location of where the A/C should be mounted. Also, make sure you have the cross-braces mounted to the underside of your roof to support the added weight. Fleetwood had SPECIFIC instructions for cutting the roof and mounting the unit as well as a poorly designed mounting kit. Make sure to follow these instructions carefully, especially cutting the hole if you have a Filon roof.

FWIW, if you have a Filon roof as I have, I would NOT add an A/C at all. Even following instructions roof cracks can still develop. Fleetwood stopped making and supporting PUP's a long time ago but the installation kit is still available somewhere online.

I second the pugs. If you camp in direct sun you will cook in the bunkends even with a 15 AC. Gizmos on over the bunkends and you can actually enjoy laying in the tent end during 90s and direct sun with no/ac.

I suggest that you get a set of PUGS (pop-up gizmnos) that fit over the bunk ends and get some Reflectix from Home Depot/Lowes and cut it to fit inside the bunk ends in between the screens and canvas flaps.

not every roof can hold A A/C unit ,better do some research first.

Contact the manufacturer for placement. It will have to be properly supported to accomplish correctly.

No roof top vent, so I would need to cut to fit. Just want to make sure I cut in the right place.

If you ever boondock you can run a 9000 BTU unit with a Honda 2K, so there is that to think about too. In many cases the A/C units have been prewired into the same place as a 12 volt fan is currently. Check either the 120 volt panel for unused wires, or it may be wired and just wire nutted off in the existing fan space.

do you have a roof vent?
