Renault Kangoo mini camper

DIY Renault Kangoo mini camper box. Camping box with retractable cooler and kitchen in the back with the seating area in the middle. One third is expanded with a box over the small 1/3 back seat. Whole sleeping area measures 188cm x 112cm so pretty comfortable for two people. There is also a 100 Ah leisure battery with a 300w inverter that is charger by the 100 W solar panel on the roof. Solar panel is connected to MPPT regulator. Things I would change and expanded in the future are connecting a split charge relay so the battery gets charged by alternator while driving and I would put in a compressor fridge because this peltier cooler is not enough during hot days. It just draines the battery.
