These appear to be roof vents so that air can circulate in the area between the exterior of the roof and the interior ceiling of the RV.

Normally drains are vented as they also are in your house. You'll probably see that one is above the bathroom(drain) and the other is in the proximity above your kitchen sink.

Very more likely than what I thought they were....thanks for clearing that up for both of us.

If you look carefully at photo #1 the traditional stack vents for the tanks are forward by the front skylight and 14" x 14" roof vent.

The vent circled in red, is in fact, an attic vent that allows venting of the roof area.

While they seem similar in appearance, they are different if you look closely.

Your black and grey holding tanks are vented through those so the odors will be more likely dissipated better and not be noticed by you or your neighbors. Some RV's have the sink and shower drains connected to those vent pipes, others have an Air Admittance Vent (photo attached) under the sink or in the wall near the shower.

Check for a AAV under your sink(s) or behind the shower if you get a foul odor inside and cannot pinpoint it as these vents fail or stick occasionally .

Your fresh water holding tank is vented at the tank and doesn't require as large a vent.

Everyone gets confused at some time, some are better at hiding it than others.

Thanks for all the feedback. Iíd already figured out the plumbing vents and theyíre located where 5picker noted them so attic vents must be the correct answer!

Do some of the trailers with raised and crowned roof have trusses? I would guess that there is an air space between the ceiling insulation and the substrate of the roof. Roof vents spaced out would allow some air to circulate in that space and keep to substrate from rotting.

Yes, our RV has trusses. There's about 6" of space between the roof and ceiling and the trusses. Here's one picture I took in ours when I was adding the second A/C. You can see there's a good bit of space in there. I was able to get my fat arm in it easily.
