I have a 2006 Thor Hurricane 30 Q. Today I opened the doghouse cover to the engine to have a look around. I saw this sensor(?) That had some fluid around it. What is this sensor and should I be concerned. It looks like it wouldn't be too difficult to replace. Here is a pic.

Looks more like a low pressure or vacuum "EVAP" (pollution control) type fitting and line. As such that little bit of oil mist deposit around it would personally not bother me one whit. I might spray it off with some brake cleaner or carburetor cleaner though. Whichever one I had handier.
It almost looks like another line is attached on the blind side. Therefore I vote along with GypsyR. A vacuum switch controlling some other flow. Evaporative canister?
I can see that. So the lower (to the right) hose would be coolant and the upper one with the clip would be vacuum. And the slight film of oil would be from the PCV part. Of small concern but you could replace an internal o-ring (or maybe two?) inside the PCV fitting. Finding the correct ones might be a bit tricky.
