Well, here it is. Finally posting a video of this arduous process (I've sent this to Jayco as well). I have hung up while on hold several times over the last two years, but this time I held out for the full hour since I am almost out of warranty (my warranty runs out next week). I have an open issue with Jayco, but not expecting much given their cool responses so far.
My favorite response they gave me was "yeah, when it comes to filling the tank that model is not consumer-friendly."
Doesn't look like the video uploaded, so here is the link to the video on YouTube: https://youtu.be/ZF1D5c_Lxko
