Where do you get a custom cover? I have a clearance problem too. I just got my new tub and have it on a deck under a taller deck (but not tall enough - by 8"). I have a trashed shoulder and have a fairly heavy cover on it (Arctic has the walk-on covers).
I kicked the idea of carefully cutting the hinge and making them separate pieces (lighter by 1/2 and no clearance probs). Then I would simply use a stretchy locking strap to hold the 2 halves together (has a pillow inbetween for sealing). If it would pop up in the center, just get a set of "hurricane straps" to keep it flat.
I can't move it myself and it'll be enclosed in a screened-in porch (closing the lower deck).
Any better ideas or anyone see any issues with separating the halves?
