Storage question

How long do you inted to store it though? Are we talking years and year for collection purposes, or is this just a short term thing?
I was thinking just add stabil to a full tank of premium, back it in, cover it up, and it should be ready to roll again next April/May. My concern was moisture coming up from the concrete and rusting the heck out of the underside. Makes sense that plastic underneath can't hurt... anything else I should be doing?
