I use a camco element and I plan on covering the element with some food grade silicone sealant as soon as I can source some.
The enclosure is from Fibox model CAB, all plastic rough size is 12" x 16" x 7", found it a a local surplus store for $30. It was tucked away in a corner. The only one they had and did not know where they got it.
I have a detailed parts list on my home pc that I will post this evening.
