My Potential windows

Hey everyone!
I stopped out at a local place that does van conversions. I asked if they have any round "porthole" windows that some conversion vans used to have. The guy there said they don't and they aren't available anymore.
I explained that I am working on building a small camping trailer and needed to find windows to put in the doors. He looked in two different back rooms and finally pulled out a pair of used windows.
These are roughly 15 inches by 17 inches. Black painted aluminum frames. Rounded corners (yeah!). And screens (without holes in them!)
These do have lots of caulk on them. The black paint is scratched up pretty bad. They are definately used. I have no clue what they were pulled out of or when.
They are about 1 and a half inch thick, which seems about right for my walls. They also have some sort of interior ring that comes with them.
The guy wanted $20 each, which seemed like a hard to beat deal, seeing as how they are the right size, shape, and have screens.
I am going back tommorow with my door cut-out to make sure these will fit.
These windows will need some TLC, but seem like a good deal otherwise.
Anything I should be thinking about or am overlooking?
