I live with 2 other skydivers and we store 2 rigs belonging to our uni skydiving club too so we generally have arround 6 or 7 rigs arround the house.
I went to our local DIY store and bought some tubuar steal table legs. They had ready made brackets at the top so I bolted them straight onto the wall with some large wall bolts. A shelf above holds helmets, the other corner has a clothing rail with jump suits on... and hey presto - our living room looks like a DZ shop, all nice and homely.
When my housemate sold his old canopy the guy who came to collect it thought we were running a kit store.
I'll post a pick of my rigrack later if I get the chance.
I suppose it does not matter one way or the other though.
One thing I do, If I know that I am not jumping for some time I take the main out of the dbag and take tension off the rubber bands. As well as take the pc out of it's pocket to take tension off the elastic of the boc pouch.
The parachute system is your life boat, and you should never think you are anal for taking care of that.
If you know that you're not going to be jumping for a while, it's a good idea to unpack your canopy (or canopies if it's going to be a loooong time). Store the unpacked canopies in dark plastic trash bags, without contact with metal (grommets, links, etc.) in a climate controlled room (a hall closet is usually best).
Of course, this means you have to repack before you head back to the DZ, but it's the best storage method to keep your gear from rotting, becoming dis-colored, etc.
*Note: most damage to your gear will come from contact with metal, rubber and moisture.
The legs were about a fiver each from B&Q - the wall bolts are arround 50p each so if you have a drill you could whack one up for about £7.50. There are probably a lot of easier ways of doing it though - this is more permanent and looks 70% cooler.
