1977 29 ft. Ambassador

What size AC unit did these come equipped with? Going to have to replace mine, it is the original that had cooling and heating capabilities and wondering what BTU rating to use. Any help appreciated.

Does it damage the roof to work from standing or sitting on it. Have a 1977 29' ambassador.
Will be working on ac unit and do not want to cause any leaks in roof. Going to troubleshoot AC problem and make sure it needs to be replaced.

Hi Katman104: I wanted the Ambassador, but ended up with a 75 Overlander. Oh well.

Yes, you can easily damage the roof by standing on it. It is just .032 thick aluminum sheeting.

That said, you know the shell is built like an old airplane fuselage. It has ribs about every two feet. You will see the vertical row of rivets that attaches the skins to the ribs. Once the skins are all riveted to the ribs and crossmembers, it really becomes quite strong.

I replaced the AC unit on my 86 Airstream. If I recall correctly I put an old piece of carpet down, then a couple of 2x6s along the ribs of the roof close to the AC. Then I put a piece of plywood over the 2x6s making kind of a bridge between ribs where I needed to put my weight. The awning seemed to hold the boards from sliding off. The AC is pretty heavy, about all I wanted to lift.

So be careful up on the roof or your body weight will dent it for sure. Note: The end caps of an Airstream are especially fragile. Never step on an end cap.

Just be sure to stand over the ribs and you will be fine.
