I have a little 'cradle' made from 2X8 scrap lumber. the engine rests on its mounts on the edge of the cradle. Nothing elaborate. The 'cradle' is about two feet wider than the engine, and a couple short vertical pieces the mounts rest on, and a couple short pieces toe-nailed on the outside to support the verts. Works great, both as a long-term storage, and a short term transport ( in the back of the truck )
