If your worried about moisture soaking into the wood, check around at a few paint stores and see if they have any paint that was returned, wrong color, etc. Usually you can get that stuff for cheap. This way if you paint the OSB you can clean up any spills and further prevent failure. Although if it was me, in the areas that the vehicle will sit, i would use plywood. Will provide better support, and you would only need 2 foot wide strips.
