As a temp solution, one can apply a solicone type material (like RV Flex) around the top and sides of the window frame. However, this is only a temp / short term solution.
IMO... It would be best to pull / remove each RV window (as shown in the U-Tube Video in the opening post) and apply soft puddy (or better butyl caulking tape material) on the "inside" of the window gap. Then, apply silicone type material on the top and sides. Thus, getting 2 layers of water protection. It would be like wearing a plastic sheet over a large fisherman's rain coat. Double the protection instead of a thin layer of plastic (like wearing a thin plastic coat on a rainy day). For a trailer that shifts and twists while being towed, it would be best to have 2 layers of water protection. Thus, I'd recommend "both" is applied. re: Under the windows lip and on the outer top/sides of the window's outer edge.
For me, I did 2 windows each weekend. 1 window on Saturday and 1 window on Sunday - while the kids slept in. At end of 6 weeks of camping, all windows were resealed. Doing this DIY project is easy. Just go "slow and steady". Works for me....
