There are no indications yet that in 2019 Jayco will be introducing any improvements in its DC Energy systems. They where not even helpful in upgrading my 2018 FD19 system as a payed Aftermarket measure.
JHub Anomalies observed:
On the JHub tablet I have occasionally observed a sudden jump from 6 or 7 bars to 10 bars when plugging into AC on arrival at destination.
Proposal: Jayco / BmPro to provide a forcible reset or power-switch / isolator / actuable circuit breaker for the Leisure Battery Supply Voltage.
Not enough solar power:
Step1: Jayco has responded negatively to our petition for a better 12V energy system. A first step would be to change its roof layout to make room for a second solar panel.
Step 2: Increase AUX charge power and improve its efficiency. Enerdrive leads the way.
Step3: Provide inlet terminals for connection of a Solar blanket. There is a cigarette lighter plug at the bed. Probably not the best for 10A charging, but worth a try.
