Newmar switched to C-Tech 2007/8'ish depending on the model. Essex was mid 2007. Other models later.
I don't know the new panel name/brand (actually I forgot the name because I didn't write it down when I saw the new panels being used on a re-skin up there several months ago
). I also don't know if it is being used on all Nemwar model lines.
Perhaps someone at Camp Newmar can inquire???????
