The issue that was un-noticed in our walk thru is the grey tank reads full although its empty, it is a brand new unit, does anyone have any suggestions for a quick fix to avoid pulling it back an hour to the dealer?
Sensors DO work and are supposed to work.
And unless I am an anomaly my sensors always work. :W
If you don't want to drag it back right off, I would first pick up a bottle of Thetford Sensor Cleaner. Add it to your tank fill with water and repeat if necessary. I'll bet that will clear up your sensors.
Although it could be the wiring to your board for the sensors which IMHO, I WOULD take it back to the dealership.
And I highly suggest that you make an appointment and WAIT in the waiting room for them to fix it.
Do NOT leave your RV there for them to pull their infamous, "get to it whenever they can" routine. You won't get your RV back for months.
Congrats on your new RV. And welcome to the forum. :C
