Well the DC-DC converter sits under the drivers seat with the leisure battery. The EHU charger is hidden in the depths of the wardrobe unit, as is the solar charger unit. Switches/display etc are on the side of the wardrobe unit.
There were a few things that put me off a single control unit. Firstly, it was too inflexible i.e. I wanted to add another switch, display or function, then it could be difficult. Secondly, there are quite a few threads on here with people asking about how their control unit works, and why it isn’t doing what they expected. Thirdly, all my eggs could be in one basket, and if it failed, then everything might stop working.
That’s just me though. I guess I know what we have fitted, and there is no black box to worry about (well not too many anyway !)
