I have a 2010 RP-171 with the 9mm keder rails. I recently bought a newer r-dome for that works with the newer style 14mm keder rails since I can't find an older dome that works with the smaller keder. I bought new 14mm keder rails from Forest River (had them cut them in half in 8' lengths for shipping) but they do not have mountilg holes drilled in them.
I took a tape measure and measured the distance between the screw holes on the 9mm keder on the camper and they appear to be evenly spaced at 6". I am guessing that if I make some kind of a jig and drill holes in the new 14mm channel at 6" intervals that they might line up.
I am kind of stumped on how to curve the keder channel. Do I just start installing on the top flat section and bend it by hand for each hole?
Has anyone done this procedure, if so how did you do it?
