Review on 🚽 White Plastic RV Plumbing Vent Caps - Replacement Sewer Vent Cap for RV Trailer Motorhome Camper - Fits 1 to 2 3/8 Inch Pipe - Roof Vent Cover Caps Kit by Tyler Cash

The cover is well made, even better than the original. It took about 10 minutes to get the screws out (save!) and put a new one on. I used RV roof sealer but I assume a good quality roof silicone would work as well. It's clean and working. Glad we noticed the damage to the old ones as we did this before the roof was damaged. This is a great inexpensive maintenance item that should be done BEFORE the old ones break down and break.
