Surf van dilemma

Hello! I’m about to start building out my 2011 Econoline into a long weekender surf van and I’m struggling to decide which orientation of the board will be the lesser of two evils. Neither of these are optimal but I want the board inside the van for several reasons. The type of boards I ride stretch from the back of the driver’s seat to the rear doors and are about two feet wide. When laid down flat it’s about 5” high off the ground at its highest point. Ideally I’d love to have a bed, some counter space, possibly a small sink, a little fridge, all the usual stuff. Any suggestions would be greatly appreciated!

Cheers!

Rack or foam blocks with straps to hang it flat or vertical near the roof?

I’d just leave a gap between the wall & cabinets so it can be slid in right above the wheel well.
