Bought a new 2016 RP182G late last summer. The Dome that came delivered with it has the narrow (8mm) edge and of course the pod has a 14mm rail. We also acquired a PahaQue "visor" with 14mm edge so I can clearly see the difference in dia. of the two edges. When I tried to work with the dealer and Forest River to get a proper fitting dome they both pleaded ignorance of any issues and offered zero assist other than a suggestion to use vise-grips to squeeze the keder into smaller size. Then the visor's 14mm might not fit. At any rate, I have used the "dome" (8mm strip into 14mm rail) several times with, so far, no pull out problems. Just need to keep the the dome strip neatly centered for about the first 8 or 12 inches during installation. My only problem is hanging the billowing mess out to dry after a rainy trip...fairly common here in the Northwest. One hint: I used a chunk of an old wax candle to lube track and a file to kind of smooth up the end corners of the rail. Overall I like the Dome.
