Still love my Cressida Wagon. I don't mind laying the bike down, as long as I get to keep the back wheel installed.
So consider "full size" wagons as a good choice. They are more geared towards cargo than passengers. Our rear seats fold totally flush with the cargo area, and we can sleep back there if we had to!
I also have a custom modified hitch-mounted bike rack that can carry two fully assembled tandems (with both wheels still on), that we use for ultra racing or travelling with another tandem team.

The interior was completely stripped down, to do the wiring (for the Lexus V8 swap) and change the heater core. I've got it about 2/3 back together. I custom modified a 95 LS400 gauge cluster to fit in the Cressida's dash, it is fully functional and communicates with the Lexus engine computer.
