Update:
I've talked to Shaw at FWC and he will be shipping me w/s on Monday.

Nope, FWC does not have the weatherstrip to support their campers. They offered me an old dusty roll of adhesive backed weatherstrip for the cost of shipping, to which I declined.
I can buy generic stick-on w/s at my local hardware store. I'm trying to put in a real door seal, hopefully that will stay put better than OEM. It's a small 5/16" rubber bulb with some sort of tee shaped spline, which slides into the aluminum channel on the door.
Shaw at FWC told me the door came from a company called Challenger with weatherstrip pre-installed. I googled Challenger, but only came up with a euro RV rental agency.
I've looked at Grainger, McMaster, etc. and can't locate a rubber bulb, slide in seal. The closest I've come is with this company:

Or with McMaster:

Anyone else have any ideas? I hate to drive down the dirt road, knowing I'm sucking a bunch of dust into the camper due to faulty seals.
