3 seats in front, rear seat for two bicycles

Hello, specialists, we want to get a new family carriage. As the title already says, we want to sit comfortably in the front with three (with child seat). We don’t need a second row of seats. In the back, besides the usual luggage for a short vacation, we should find two undisclosed MTBs. Optionally also a mattress for sleeping. At best at the same time. It would also be nice if you then manage on the highway 150km/h. The vehicle should not overdime After all, one wants to park it somewhere. The whole thing is clear again: I hope my female wishes are not too overworked and egg-legging wool milk-like.
