Round windows don't slide. The 12-inch listing says they isolate temperature and moisture, block rain and debris, and give you a view. There is no screen bullet on the page we read, which fits a fixed pane. Don't buy one expecting a vent.
The 12-inch page says the rough opening is a 12-inch diameter and the wall fit is 1.5 inches, with slightly thicker walls up to about 1/16 inch still acceptable. It warns that a small gap at the trim ring can show up and that a small gap is acceptable. A large gap is a leak. The 13-inch and 15-inch listings were in stock with matching titles. Read each one for its own diameter. We are not copying the 12-inch wall sentence onto the other two.
A round hole in an RV wall is not easier than a rectangular one. The flange has to land flat. If you are replacing a cracked porthole and the hole is already round and the right diameter, this is the straightforward swap. If you are cutting a new circle in a laminated wall, stop and decide whether you actually want a window there.

Works in its favor
- 12, 13, and 15 inch listings, all live when checked
- Fixed pane: fewer leak paths than a slider, if the flange is sealed
- The 12-inch listing prints a wall thickness
Holds it back
- No ventilation. It is a window, not a vent
- Wall spec was read on the 12-inch size only
- A trim-ring gap the listing calls acceptable can still drip if the sealant is thin

Questions worth answering first
Can I open it for air?
Not this family. It is a fixed pane. The breathable rectangular windows are the ones whose listing talks about a rainy-day opening.
