Dometic exterior vents for 2000 17SD
I enjoy a challenge of looking for obsolete parts but am frustrated by the lack of any part numbers that are currently offered. I have a 2453 model which indicates the part number for the exterior vents are LS300. I just measured it at 13 in by 21 inches. The vent is OK the frame around it is cracked at all 4 corners. Any hope of finding a replacement?
