I never thought my simple question would get this level of discussion going?
A good solid well supported storage structure just makes plain sense to me and that is what I did... 8" CMU blocks placed on 12"x24"x2" thick concrete slabs spaced 4' on center. I used my 4"x8" sill plates as the rails and placed 4x4's on top 2' OC, leveled with my transit dead nuts, timbers stickered with kiln dried 2x2's. This support bed cost me nothing but a little extra time.
As a homeowner constructing a once in a lifetime project, the extra labor involved (not much) is effort well spent to protect my investment of both time and dollars. I dont have time for trial and error or the $ to learn the hard way.
