RvFNG76 - I started to get a headache dealing with that other stuff so ... I'm taking a break to do something I know is productive.
One source is
Steele Rubber Products.
Another is
Trim-LOK.
I kinda prefer Trim-LOK because they also sell other restoration products, such as drip rails. Likewise, they sell tools, supplies, and consumables.
However, that's a personal bias ... I really don't have a basis for making a recommendation one way or the other. So, look at both (and other possible sourcea) and decide which may be best for you.
You can find other sources by googling "windshield gasket" or "windshield rubber gasket." (Variations on those search keywords may bring up other sources.)
In any case, you're going to need two pieces of information. (1) The thickness of your glass and (2) the thickness of the metal or FRP windshield flange on your motorhome's body or front cap.
