If the power pedestal is close to the rear of the Montana, I make small dia. coils out of the excess length of power cord and put the rear stabilizer down though the middle of it. That way, a thief would have to unwind the length of the cord from around the stabilizer quite a few times. Dragging 30 feet of 50 amp cord around the leg 6 or 7 times is gonna take some time, make some noise, and wear a fella out.
I wonder how strong of an electromagnet my stabilizer leg is??
