I've had a 10k lb 2 post hoist sitting under a tarp for 8yrs now. I've never even unbolted it from it's shipping braces. I originally baught it to put it in the shop I was renting. That was until the owner of the building said anything affixed to the floor or walls belonged to the building owner. That was the begining of the end of that shop space. Once we got our shop done, having 2 open bays always seemed better than having to fight a hoist when it wasn't needed. I'm thinking of moving my big heavy racking around behind my south bay, adding a roof and covering the sides, and putting the hoist there. We'll see how far that goes.
