I haven't kept two at once, but I know several folks on here do and will probably chime in. I've seen several very creative setups on here. I like the double decker front opening setups. They seem relatively space saving and could probably be built into a large dresser or tall piece of old furniture. You could also try simply stacking two crossfires on top of eachother with some kind of cubby or spacer in between them for storage or running wires etc.
