Thanks!!
It's a Femco brand weatherbreak. Wasn't exactly made for my 3203, because Femco and others didn't make them for the 3203 at the time, but was able to make it fit fairly descent. I purchased it a couple yrs ago from a company on e-bay that had them for a descent discount over dealer costs.
The plexi rear window is easy to make and install,(I use 5 zip-ties), and the manual wiper blade was also an e-bay special I found in the boat section there. Works wonders to clear the snow that blows back!!
FEMCO, Inc. there are other mfgs of weatherbreaks and enclosures out there too.
