"On my old Travel Trailer, you'd pop the top, pack some bearing grease in it and you're on your way."
Well, you could try that and it might work. It depends on what is squeaking, it could be the thrust bearing, the gears in the gearbox, the motor, etc. Once you get it narrowed down it might not be that hard to take care of. But if it's the thrust bearing it is doable, but not so easy. Depending on what stabilizers you have.
