has anyone or can you install rooftop ac unit in the rooftop vent?
Yes, if the vent hole is 14 x 14.
I am guessing that you will need additional supports.
Our 86 Coleman has a foam core roof lined with aluminum on top and a thin 1/8" board on both sides of the foam core. To support the AC, they used a single brace that spans the inside, under the whole roof system, and covered it up with a tin panel painted white. The brace is supported by large screws on the outside, screwed into the brace on the inside. Doesn't really look bad and you don't notice it. The power cable can be run under that tin cover as well.
This is what the inside brace looks like for roof a/c install... Hopefully your 14x14 inch hole is centered on the roof and not off to one side although it probably would not make any difference.
