Hi David,

Interesting solution. The only problem with that solution is that it
effectively doubles the load on the poptop hinge. I am not sure that
the pivot in the hinge will stand up to that sort of use in the long
term.

Why not extend that fulcrum forward over the luggage rack and then
use a hydraulic or pneumatic cylinder or a remote-powered scissor
lift  to the roof lift upwards. A pair of steel brackets attached to
the forward edge of the rear poptop section could come forward about
6" and be joined to a center yoke connected to a lift mechanism
anchored to the luggage rack. The touch part with this approach is
finding a lift mechanism that would extend to the full height  of the
roof and fit within it when compressed.

This would contain the lift inside the perimeter of the vehicle and
needn't make it any taller than it already is.


Happy Trails,
