Here is our fix. We almost exclusively camp off “primitive” roads and the original glass lamp survived two of those trips before shattering all over the floor.
Frosted round plexiglass and white nylon spacers. I think it cost me around $15.
I wasn’t able to readily find replacement glass.
However, I did order some body pieces
for our 2104s directly from Forrest River. Shipping cost was a bit excessive in my opinion, but they got me what I needed.
They probably can source a replacement.
