I cut a big hole!!! IN MY CAMPER ROOF

I was looking for 12v electric hatch motors (for my boat) and came across some very inexpensive and fairly strong screw jacks on Amazon. Might be worth looking into for your project. They were like 325 pounds lifting strength and 24” of rise. I’ll see if I can find a link.
