I agree with Carl as I already have an amp underneath the passenger side and a 1 ton floor jack underneath my half of the bench seat.
Carl, what about a slight lift at the front of the seat bench, a 6" or so drawer-slide forward incorporated into the seat bottom, and then hinge to open fully? That would clear the seat back so that it would stay open at an angle without the need to hold it open.
Cosmo, I'm talking about fully operational robotic technology, man! I want servos, switches, hydraulic dampeners, 3-way adjustable mortising jigs (I made that up), that sound that the automatic sliding doors on Star Trek makes, maybe some smoke.
