Average shell load limit?

[Malysoun]

Anyone happen to know the average load limit you can put on a fiberglass shell?

There's a Ford Falcon just down the road from me with an AC unit on top in the place where my busted skylight is. And that has me thinking of just replacing the skylight with an AC.

The AC unit is 90lbs, it has a 130lbs moving weight. So they generally suggest the shell support at least 200lbs.
It's probably not a good idea to just assume the ladder on the back means it'll hold up to a person or two up top.
I'll probably be testing if it'll at least hold me, it should be good if that's the case.

Couldn't guess at what the manufacturer expected on yours but that's where my AC is on a very similar designed Coachmen class B.

Is there a power source in place? I've heard that on RVs they will place a 120 volt source in there regardless of whether they put the AC in place or not. If perchance you have a 120 line in place to that point then they likely built it to hold up an AC.
