Roof weight limit?

[rnrphoto98]

I am looking at putting a new vent in my 88 Elandan 32ft.  How much weight can that roof hold?  I am 350lbs and don't want to do more damage by getting up there.  Any Ideas??

Thanks

I don't know if there's an actual "weight limit" published in any known publication.  However, this question was posed in a slightly different way.  Check out this topic:
