I've been using a Harbor Freight 1/2 corded to raise and lower my 5er landing gear and stabilizers, for several years. On the two occasions I did not have an electric site I just fired up the generator. It is also much faster than the electric motor that came on the unit and which quit working years ago.
I also use a Harbor Freight cordless 1/2 mostly for lowering the 5er or raising the stabilizers. Chores that need a lot of turning but not much torque.
I do not know the torque specs but the corded drill will lift the front end of my 10,000 lb loaded 5er with no strain.
