I've seen them make that OSB over at CalTex in Nacogdoches, TX and that stuff should hold up just fine for what you want to use it for. If you've got it inside your "garage" and not in direct contact with water it should hold up just fine for your temporary needs. My concern would be if your pallets are going to be able to hold the weight at all four corners without some type of additional support.
