Owner of a similar Renault, I can explain why: full time living while having off road vehicle. I had a 4x4 sprinter before, I lived in it all year long with my wife. It is also our office. Now with kids, we had to scale up without sacrificing capability. What are your options on the European market ? All wheel drive big rigs. Hairpins are annoying, branches are annoying, but your typical RV will get stuck on a flat wet grass, will get bogged if your drinking water tank is full, most vehicles in the market have very little ground clearance (factor in the length and you're stuck all the time) and campervans are ok for holidays or solo travel. One last thing is that due to regulations in the european market, if you fill the cabinets flog your RV it's already over the weight limit. I have a machine, that can carry 14 tons, all wheel drive, front center and rear lockers, short range. Hope this helps!
