We found another compartment on the 2012 Georgetown
Thank you for the reply. My Husband says that there are no valves in the propane compartment for water. However, we did find another smaller locked compartment on the passenger side of the vehicle just above the drains underneath which I took a picture of. This compartment has two twist off lids. Way back in there in the right hole is a valve which must be to drain the water, and the left one must be the water pump. It's very strange that the dealer didn't tell us anything about this. I will go to the site where it is parked again, and snap a picture. Thank you again for the information.
