While full electric could be possible, the only hard part for me is the first two feet of the lift particularly in the front where it is hard to lift in the middle. The rest is very light and nearly opens itself.

Have played with a hook and A-frame system that did not work very well but think a automotive window regulator so could be hand or power, might be a basis. One for a station wagon rear window would have enough travel and force. OTOH a simple lever might be all that is needed. Guess I need to look into it again.
