Kev ( Pusey Bear) has one in his van too, he also has Bluetooth voltage monitors on both his batteries so he can see and record what they are doing. He posted some images which I'm sure he won't mind me adding here.

Above is a voltage chart showing a 5 day period of layup and the solar charging traces, the purple is the leisure battery and the green is the starter battery, you can see how the Gizmott maintains the starter battery at a near identical voltage, just 0.1v difference which is the forward voltage drop of the ideal diode module.

All good with mine. Well I assume so. I dont monitor mine but you can tell from the Swift control panel the cab battery is always fully charged.
