The 1968 Forester model 14 That Im finishing now has a buyer and they want rooftop air. I took the call as I was literally putting together the supports for the rooftop vent. They told me they wanted to add rooftop air and I told them good timing! another week and I would be tearing stuff apart to make it happen. I don't have the skin on yet so everything is accessible. I believe the Forester can handle the weight. It has 1 1/2" thick walls and 3 inches of bent plywood at the top of the wall to support the roof. This model is also narrow. About 80 inches wide. The rooftop vent on this model sits between the wardrobe cabinet and kitchen cabinet. Theres is only 43 inches of free span there so it seams like it will have good weight support. I have 2 1/2" of clearance between cabinet doors and ceiling when the are open. I don't think they will interfere with the A/c control facia. Here are my questions. No strong feelings out there about a better location? I haven't cut the opening yet. Is the sloping roofline a concern? Do the A/C units need to sit level or is flush to the slope ok? Do I need to beef up the supports for the entire length of the ac unit? or just the ones that support the opening? This trailer electrical is a two fuse unit with a fridge. I suspect Im going to need a separate fuse/breaker. 30 amp shore power? Whats a good installation charge price in addition to the A/C unit. What else don't I know!!!!!! I just started the OEM Roof vent opening supports. They are 1 1/2" x 1 1/8" knot free material. I can make them wider.... IMG_7522 by Campurist, on Flickr

How much does the AC weigh?
I think you'll need a separate line to the fuse box or the lights will dim when it kicks in.

Now I'm concerned about the interior controls and vent shroud. I found a coleman but it sticks down 2.33 inches from ceiling. My cabinet doors swing out 2.5 inches below the ceiling ... not a lot of room for error. Yes I may buy a 4 breaker box.

90 pounds seems like a lot of weight even with Forester framing. I'd probably beef it up.

I would try to work some angle iron into the AC framing members. That's a lot of weight for even 1.5" of wood to hold up.

All good advice . I am taking comfort in the fact that the supports for it will cross parallel to the edge of the wardrobe cabinet and meet the kitchen cabinet on the other side so it's 43 inches of free span . I will makes the beefed up supports run the entire width of course . .
