Do they still make something simular just not the Bargman?
Yes George, they do. I bought one of like shown below. The problem, and maybe you can figure it out, is the strike plate on the Scamp
door. You'd also need to shim the door latch (on the inside?) because these are made for thicker RV doors than a Scamp. However, I have seen one installed and it looked/worked great! Maybe if you get it figured out, you could post the "How To"?
BTW: I borrowed the pictures from this eBay ad, $32.99 BIN: RV Entry Door Latch
