Experience with current Renault Traffic

Hello together, we need a new car (6 seats). So far we had the VW Caddy Maxi in focus for this. However, we still fluctuate and have driven the Renault Traffic Probe the last time. You notice here nevertheless strongly the transporter genes, but from the space offer already a different world than a Caddy. I would generally interest your experience with the current traffic. What bothers you and what can be seen with a view of a family car positive. How do you come with the back row of seats right? The benches look very bulky after all. The variable rail system is only available from the space class, can you retrofit it yourself? Is there any experience with the lying area? Can you sleep on it for a longer time? Greeting and thank you
