Keeping a tube/fabric airplane outside

Hi guys. I've got a bit of a question for the "veterans" of the group.
I've been looking at some aircraft as possible purchases, and, being a
fan of older styled planes, a lot of them are tube/fabric designs (I'm
really interested in an EAA Biplane or other similar design, though
I've also been looking at some Aeronca's and such). Now, I'm on the
hangar waiting list on my local airport, but at best estimate it'll be
5 or 6 years before I actually secure a hangar.

Naturally though, my local airport has plenty of tie-down space
available. So, my question is, how bad would it be to park a
tube/fabric plane outside for this period of time? I'm on the South
Carolina coast, so snow is a very rare thing (I'll probably get the
hangar before we see snow again around here ), but it does rain
fairly often and it can get quite hot/sunny.

So, is it feasible, or should I hold off on the purchase?

Thanks.
P.S. I check most of the aviation Usenet groups regularly, but if you
wish to respond via email don't use the one in the header (it's not
valid anymore). My address is: mbgaski at infoave dot net.
