29.5 BHDS Outside Propane Port

[datx]

Hello!

On my 2017 29.5 BHDS there are two external propane ports (one at the back of the trailer, and one near the tires on the side).

I generally use the one on the side. On this last trip, when I plugged my grill in, the gas flow was so low that the grill sort of "flickered". I tried two different hoses and had the same result. I plugged the grill into the rear port an everything worked fined.

The water heater and stove work fine.

To that end, has anyone else seen this? Seems like maybe the port is "dirty" or something is obstructing the gas flow somehow. Admittedly I forget to plug the port back up after I'm done using it.. Maybe it is dirty? Is there a way I can clean/inspect it before I'm forced to drive it to a dealership for service?

Thanks!
