On my spring list was caulking every window and the main door
I have a 2016 25.2 I was shocked when I removed metal flashing around door there was at least 1/4 inch to 1 inch gap no insulation or cauck, found same issue around most windows but smaller gaps, sealed all with best silicone product I could find. after tackling inside, did the same to seal everything on outside of RV
