Outdoor car for family of 4 with overnight stay

Hello dear community, first of all: Happy New Year!!! We are a family of 4 (children: 4 and < 1 year) who are looking for a new car. We want to be more on the road on the weekends (new intention) and are therefore looking for a car that is: * For longer distances (i.e. around 150 - 200 km) pleasant to drive with 2 children * Good storage space, so you can also leave things in the car * On site can be used as a sleeping place for 1-2 overnight ungen (also here: With two children) – if possible without having to go to the campsite * Also sometimes can drive well over uneven terrain * Also in the city is well usable We have already thought out the usual suspects: * T6 California Beach: Does not feel so good from the price / performance * RV: Does not go in the city * Caravan: Actually a nice option, but then again the problem with the parking space and you should always go to the campsite * Pickup + Famil ien tent: Could you do it too – but then the problem is that you always have to go to a campsite Do you have an idea that I missed? Is there someone who likes to do similar tours and is happy with his car? Best regards and thank you for your help C
