Just offhand a starter motor would have plenty of torque, the problem would the gear train and synchronization. I keep thinking a hooped L-bar could handle the initial up and out to a point where the movement is mainly horizontal and easy. For the forward modile it could rest on the tongue bars, problem would be a pivot point about three feet behind the rear bumper.

Personally find it harder to move the slide (broke the handle first time I tried & not in the parts catalogue, anyone know a source ?) than to lift the modules after a bit of adjustment.

Only real issue I had was if too easy to lift, it becomes hard to latch down.

My Vixen has an air cylinder to raise the pop-up roof but it only needs to move about 18". Modules need to move about 60" in an arc so would require either a gear or track.
