This is a really impressive VW camper modification! Turning a standard kit into something completely new, with the addition of PF steering and driving is a huge step up. All the changes, from the interior to the opening windows and the new color scheme, make this look more like a full-fledged MOC than a simple modification.
The integration of electronics is another strong point. The IoT brain that controls the motors, including a real motor with rotating wheels, is an impressive solution. Particularly pleasing is the use of RGB LED for a spectacular visual. As for the jerky steering, it might be worth trying to remove the clutch so that the motor can work at full power.
