Any advice on storing jeep hard tops?

Have built up several jeeps and discovererd several new products from 4wd.com and quadratec.com. I built my own winch system using their design and it works very well. I highly regimens it. Its up and out of the way and doesn't get dinged by the mowed or kids bikes. Before I put it up they tried to use it as fort and all I could see was the dollar signs if it got broke.
