My vision lift is being shipped to me in the next few days. If waiting isn't a problem, I'll shoot you some photos once we get it installed.
In my case, the tub is 38" tall + 8.75" raised off the ground with cinder blocks and 3/4" plywood. The cover itself is 45.5" tall folded, as I recall. So, with the extra ground clearance below the bottom of the hot tub, the manufacturer felt that we could configure the lift to set the lid on the ground and be almost flush with the top of the hot tub.
If our tub wasn't 8.75" up off the ground, then the cover would still be taller than the side of the hot tub, even with the vision lift.
