Leaking window

[Jaficek1]

We have a 2015 Jayco Redhawk. We are traveling cross country and the bedroom window has developed a severe leak when rain is coming down.
Can anyone offer a temporary fix? If we use tape to try to seal the window, will it damage the exterior finish?

Temporary use Duct or Gorilla tape. Replace after 3 to 4 days so the glue will not leave much residue…….
