When its warm and sunny and the rubber gasket around the window is pliable you can pull it out and clean it. You will be shocked how much dirt is in the gasket folds or just on the inside surface. Some of that is ending up in the window channel

I lube the inside portion of the gasket with silicone spray, wipe it off and press the gasket back in where it came.from

I took a small air compressor and blasted the weep holes. I did see a small chunk of debris come out of one hole. I kept blasting and feeling for full air flow from all the other slots. Also even though I don't believe it's coming from the top, I laid a tight silicone bead over the top seam and a few inches down the side. Very frustrating leak.
Its now degraded the wall where my table bracket is mounted to. I am going to have to make a larger bracket to catch more undamaged wall surface.

I hate the way RV's are made.

In photo above showing s corner of the inside of the window I can see that it is a clamp style ring. Multiple screws on the inside edge pull the window in from the outside.

You can download the window mfg install guide

Easy to remove. Have a helper outside to support and catch and vice versa to install.

Clean inside window edge and apply butly tape to install

Tighten screws in alternate sequence like lug nuts. Tighten slowly over 3 days. Usually by day 3 only a few screws can draw window in any more. Don't overtighten. Clean up butly from exterior. I clean after each tightening.
