Missing something under the kitchen sink

[Geopixie]

Hey all, I'm sure there is something I should be able to find on here but I don't know what I don't know so I don't know how to search for this so apologies for I'm sure is a stupid question. This is my first RV and I bought a 2009 bighorn 3580RL from an individual. I'm hooked up to city water but the kitchen sink is missing something where the water is supposed to drain ... can someone tell me what should be here?

If that pipe hanging down comes from the sink and the other stub goes to the tank then you need a P-trap.
Need to know the termination of those two white PVC pipes.

Peace

Like Cookie said. Depends where the pipes go. The one going through the wall is most likely the one that goes the the holding tank (drain). If the other goes up a wall, then it is likely the vent to the roof. If it's connected to the sink and there is no pipe going to the roof, then you will need to add a Studor vent in addition to a P-trap. Though I don't have a Bighorn, I am including a picture of my drain. The red arrow points to the Studor vent. It would need to be placed higher than the P-trap. Hope that helps.

I'm not at it tonight to take another picture to better explain but I don't think it's a ptap because it doesn't come directly from the sink drain it takes a few turns before dropping the water off to nowhere. I was thinking that maybe there was a under the sink tank for some but I don't know if that's a thing. All the other tanks have been removed from it which is why I was thinking maybe it's how connected to all the things they disconnected.

Here's a better picture the p-trap is there

Kind of strange. In the photo , it looks like it’s joined to the sink drain. That would be weird for a vent, the way it’s positioned. If you could run some compressed air or water (seal around the opening), you might be able to determine what it leads to.

The vent is there as well ... at least I'm not the only one confused lol here are some additional pictures to see if that helps.

I have a couple of questions for you about the rig:
1) When you purchased the RV did the previous owner have it set-up on a seasonal or permanent site?
2) Trace the white PVC pipe and see where it connects to the sewer system
3) Just curious if the white PVC pipe bypasses the gray tank for the galley sink, does it?

With the white PVC pipe in place, I am just wondering if the previous owner ran this drain straight to the sewer outlet and bypass the gray tank.
