Just a thought...Past 5th wheel we had, the bathroom sink had a piece of pipe that went from the sink drain and over and made a 90 turn and down to gray water tank. The sink became real slow, I clean out P trap couple times, with no luck. As it turned out, the pipe that went from the P trap to gray water tank became loose at the fitting and vibrated down (but didn't leak) and the drain pipe was no longer running down hill. Sink would drain all but last 1/4 then water would sit there. Easy fix once I found the problem.
So double check to make sure drain pipe is still running down hill.
