Slow kitchen sink drain

I have 2013 Tuscany, 40ft Class A.
I have a slow drain in kitchen sink, Iíve checked the trap and was clean. We have used a plunger, and that solves the problem for only a minute or two, then back to same problem. Weird.
Any suggestions??
Thanks in advance

In most kitchen sink applications there is an under sink vent. Make sure the vent isnít blocked or dirty. If it is then that would be a possible cause for a slow drain.

We just purchased a 2020 Tuscany 40Rt and had same problem coupled with the shower. It wound up being an improper placement of the vent. A new vent had to be run to correct the issue

The vent youíre looking for will be under the sink but up high near the counter top. Itís commonly called a Studer vent (which is a brand name) and it just screws on. Sometimes they stick closed. Remove yours and you should be able to suck but not blow through it. Often just getting it free will work but they are not expensive at big box home centers.
