What do I do with this?

Do I caulk over this strip of plastic in the front window? It looks like it isn't seated all the way in where it should be. Also looks like it has leaked inside at one time & the PO did some caulking inside. I'm removing all the outer caulk & redoing (hasn't been cleaned up all the way yet, obviously), but am not sure if I should remove the plastic/rubber gasket type stuff & just caulk the outer window with Parbond, etc. Is there a source for new gasket of this type? Should I just caulk over it? Waiting for all of your advise! Thanks in advance.

I wouldn't caulk over it -- it should be sealed from underneath (between it and the window frame. If it is not broken and is only sticking up here and there, I would gently lift it up enough to apply the parbond underneath. Then gently push it back in place.

I wouldn't do anything with that seal until you reseal the perimeter of the window frame first and then recheck for leaks. The seal that you are refering to is a "U" type seal that the window is bedded into. If it leaks then, I woud at that time cut the edge off and reseal with the sealant of your choice. All the windows that I have pulled out of my 71 GT were poorly sealed aroud the perimeter.

That is a good spot for Alcoa gutter seal - anything resembling a crevice or gap on frame or gaskets as shown in your photos got a thin line of it applied on my '73 and it is holding up well...

Hi Becky -- That looks a lot like the plastic strip my '74 Argosy had. The lower horizontal strip allowed water to collect and leak through. The interior caulk job you show wouldn't have addressed the leak that destroyed my front floor. I'd sit in the trailer during rainstorms and observe failure of several of my efforts -- nothing worked until I did something similar to what Wabbiteer is describing. I've seen Alcoa gutter seal recommended before. I used Sikaflex 221 injected through a small opening irrigating syringe (with tip cut off enough to allow flow). That didn't seal quite the way I wanted until I ran my fingertip along the joints to press it into the cracks.

When last using the Alcoa 'toothpaste' style tube I crushed the aluminum spout a bit to make it oblong for a more narrow bead - but since you get one chance with the stuff as it skims over instantly the extra length at the nozzle 'flow' point seemed to help too...
