I love the Kepler One too, but I can't understand why they didn't store two chairs for outdoors on the tailgate like the Cali. Maybe VW has still a patent on it ? Also a table for outdoors is missing, as in the sliding door there is the inside table, which has no legs.
There is plenty of useful small storage, easily accessible and easy to use, but you can't store big items. Where are you going to fit the leveling ramps? Where the outside table+chairs? Drive away awning, outdoor carpet, kids beach toys, possibly a beach trolley?
You would have to store all of it inside in front of the toilet or living area, in this way negating the very advantage the Kepler 6 has, while en-route using the toilet preparing a meal, eat inside in inclement weather. Once at destination you have to offload all this stuff somewhere outside in order to use anything inside, including the poptop bed as you access it from the rear.
With the Cali everything is in the boot, fully loaded you can still cook, access the fridge, the bed upstairs and the table inside as well as the one outside +chairs.
The more I look for Cali Killers, alternatives, the more I realise I still have the best vehicle.
