That's a layout I hadn't considered. I'd been set on me and my wife sleeping on a bed farthest back in the van. Too much looking at SMB layouts!
So ert01 - you have a total of four bucket seats plus the bed/bench? The driver and passenger, plus two more passenger buckets as the second row? Then the third row is a bed/bench? Behind that is a mattress on the floor?
And you just leave the car seats attached in the second row buckets all the time I assume?
