The first item I noticed with our R-Pod 179 was lack of peripheral window view in the dinette slide out. I measured the side wall and found a 21" x 14" window that would match and be suitable.
It is from www.Teardroptrailerparts.com - window WD06.
It arrived quickly and came with an internal finish frame and mounting screws.
My installation took longer than I thought. Hopefully after sharing my issues, it will only take about an hour or so.

Make a template from cardboard and trace it where you want it on the inside wall. It is a 14 1/4" x 21 3/4" cutout with 4" corner radii. Drill an 3/8" jigsaw start hole just on the inside of your template mark.
Then center and place the template on the outside wall and use a Sharpy marker, trace the cutout.
The wall is 1-11/16" thick. I put masking tape on the jigsaw bottom plate as to not scratch the finish.
Use the jigsaw with a medium fine blade to cut out the opening.
About 2/3rds the way up on my opening, I ran into an aluminum channel I assumed used for additional wall strength. You can see it on the cut out wall section photo. I changed jigsaw blades to a metal blade and easily cut through the aluminum. (Ask me in a year if the slide out has collapsed or not...)
Putting in the window should add some strength to the wall, so I'm not that worried.
The screws that came with the window are not long enough. You need 15 8x3/4" black capped window screws.
Pre-drill the finish frame screw holes on the window frame using a 5/32" drill. It's hard, but try to center all holes the best you can.
Clean the outside portion of the opening with acetone before fitting the window. Put a seam of good silicone sealant on the rubber window seal and place the window into its opening - best to have an extra person to hold it from the outside.
From the inside, screw the finish frame onto the window using the 8x3/4" screws. I would cover the outside portion of the inside finish frame with masking tape to protect the finish from drill burnishing. (I have to paint a few blemishes on mine!)
15 screws later one is finished.
After the silicone set, I cleaned up any extra on the outside with a razor blade and acetone.
Issues I had:
I assumed the screws that came with the window worked - no. Only after I put silicone on the seal I found this out. And I tried doing it by myself. Best to have someone on the outside to hold the window in place while you are securing it.
Cut the window opening from the outside. I tried from the inside and it was hard to see and cut a perfectly straight cut out line.
Once I hit the aluminum channel bar, it was too late to back out of this project!!
You have to drill pilot holes into the window frame for the correct screws and make sure they are centered as well as you can make them.
Hope your window addition goes faster and smoother with what I've learned.
