thanks for the pics MOD Guy. looking at your setup makes me think I got ripped off. My Surveyor should have never left the factory with the lack of seals on the slider.
I think if a seal set from an 07 like yours is backward compatible it would be worth a few hundred to put it on mine. My local Rv shop has tried to get an answer out of Forest River about this but no luck so far.
My unit must have been made on a Friday afternoon or Monday morning... While attending to some other issues inside the camper I found missing fasteners on panels (only every other one installed...) wiring that wasn't thoughtfully done, and an overall lack of attention to small details.
NOT what I expected from a FR product. Now if only I could contact Warren Buffet and complain.....
