I was looking for clearance light ,stumbled across "Bend Trailers" they tons of RV parts. 600 parts in vents, skylights alone. Followed 100s of links from here never spotted this place in tons of searches for RV camper items before. Tons of small oddball what I'm sure hard to find items . I don't know how they could have so much unless they drop ship from dozens of other places. I wouldn't know the prices of 1% of this stuff from Lippert , Carfree, A & E ect. but the items I do know are pretty good. I did find many nice looking green outdoor matts to go with MH kind of scarce besides cheap astro turf. If one place to look besides Amazon and Ebay this might be it especially if your not sure what to call that little rv doodad .
No affiliation just found it an hour ago and have been looking through 5% of items.
