Recently had occasion to try and ad water via the Country Fill option, when no "City Water" connection was available. Followed the instructions to a tee, but pump would not draw water from a container. Went to the dealer today for a "learning session" and they couldn't get the "Country Fill" option working either, even after calling Jayco's tech support for guidance.
Now the fun part...one of the "senior/experienced" owners came by and pulled the cone shaped screen & washer out of the fill connection, turned it around and put it back in "backwards" so it pressed on the relief valve, and voila, all was good! We think this "trick" should be in the owner's manual somewhere, but none of us, including the Jayco techie could find it, and it wasn't mentioned by anyone we contacted.
Minor issue, but might be something Jayco could make clear in their instructions. Our dealer will be adding it to their demonstrations in future sales. One never knows when the need for a little detail like that will come in handy!
