Replace plumbing vent covers

[phillipank]

This is for a 2021 Keystone Cougar 27SGS 5th wheel.

I want to replace these plumbing vent covers (attached photo) with flat ones but I can't seem to find the right size, or even know where to measure. Ideally I want to avoid removing it from the base and messing with the roof sealant. Anyone know where I can look for replacements?

Thank you,
Phillip

Your going to have to replace the base as the mounting tabs are gone.

They are a standard size:

OK I think I saw these but they look larger than what I have, but I may be measuring in the wrong place. I'll take the pro's word for it. Do you know of a site that shows how to remove and replace the sealant? That looks like a job. And where do I get that?

There should be 6 screws that hold the base on. When you buy a new one it should come with the putty you use on the bottom. Any plastic scraper will get the old sealant off. You only need to remove enough to get the vent base off. When done reseal with Dicor self leveling lap sealant.

Perfect. I'll give it a shot. Thanks so much for your help!
