Winnebago Adventurer window seals

[Brandon1078]

1998 Winnebago Adventurer 35WP...Anyone know if I can still get seals for my windows? When I bought my Winnebago, the man I bought it from said he had the front windows replaced a few years earlier. I’m wondering if the guy that changed them out, tried using the same old seals. There are ripples in the one on top of the window and there is a gap on top right (passenger) window. Can I buy these seals and take them to local glass shop or do most glass shops just fabricate things like this in-house?

Here is where it’s leaking. I found after removing trim. If I put more caulk/silicone there, it’ll just find another way in, don’t you think? I think I’ll have to stop it from the outside.
