I am just seeing this thread, sorry for being slow...

Cory, I hope all is well now up your way.

As an alternet idea...

My thought would be this. Go with laying on the side. Only store the trays vertically, transporting them like beehive 'supers'. When you are not using your fleet, as in being 'in ordinary', have them mount into a 3d picture frame, to be displayed on the wall. This maximizes use and provides convenience in storage. I would use generic shapes so the groupings could be customized. This would have to be a delux option, but with our creative crew members, I bet some creative juices are flowing. Personally I would prefer the other items to be stored separately. One other advantage would be if they were in linked pairs, they could be displayed at the game site as in an open book standing on its edge, for easy ship choosing.
