Air cylinders in all shapes and sizes exist out there to do the work of
lifting. You can use an electric or engine driven air pump, but the
electric is likely the simplest to work with and easier to install. A ten
or so gallon air tank fits fine anywhere under the body and will store the
volume of air you need to lift the lid at a rate you like. You'll be doing
a bit of math unless you like trial and error.
You can also, with proper counterweighting or air springs, use electric
motors such as ones used for window winders. These things are strong as
hell but don't run so fast.

Folks who will likely have useful information and/or equipment will be
shops that do RV's, semi trucks, and those low rider shops, since they do a
good bit of that stuff, including pneumatics in addition to their usual work
with hydraulics.
