I find it a pain in the butt, plus sometimes when you want to park a car under the one on the hoist they can get really tight and the lifting of the car as it goes over the hump can be tricky. When I had my '57 Chev up on the hoist I had trouble backing the Overlander tonner under it. I had to remove the rear wheels off the Chev as the Overlander fitted but when it backed over the hump the roof hit the tyres of the Chev.

It is also harder to push a car over the hump especially if it is a body on a rotisserie, and you want to wheel it into the hoist to lift it to then put it on a chassis (which is also hard to push over the hump).
Other stuff like trolley jacks, transmission hoists, tool box/trolleys etc are hard to wheel over it. Once you use one for a while you'll see what I mean.
