Help identify roof vents. I'm clueless.

[Woodworker]

We had our 3811MS washed by a "Pro" crew while staying at S Padre Island. I think they got their garden hose hooked under a couple of these vents while on the roof.
I need help identifying them, what they are called and where to buy replacement. The large white one is about 6-8 inches in diameter and I'm guessing they are a attic vent of some time. There's one just like it on the rear, unbroken. The two black ones are forward of center and I'm just guessing they are tank vents.
I'm clueless, please and thanks for any help you can lend with identifying these.
Thanks.

The big ones are "mushroom" vents. They come with two pieces but you only need the top part that screws one. Here is a link to one place to get them Clicky

The smaller vents are "Plumbing Vents" and are available pretty much everywhere. Here is a link to different vents Clicky

The black ones are tank vents. I guess they are intended to keep debris out of the vents but still allow the pipe to breath. When I lost the top off one of mine I replaced it with a larger size abs cap. Ran a screw through the sidewall of the cap directly in to the pipe. Think I put a 2"cap on an 1.5" pipe. Been there for years. with out an issue.

On past RVs - I have had those caps get dried out and crispy. The power washer may have chewed up the weak plastic. Either way it’s time for new caps.

Just curious - where did you stay at south padre?

We stayed at the Cameron County Park Isla Blanca. Had a front row seat to the ocean. Stayed at the KOA a couple of years ago, but it's really crowded.
