Hopefully a garage door opener would last a long time being spun for hours on end. They're designed for <20 sec bursts a few times a day. I would think it would hold up though..
I thought about that too, but I figure that the rotational load of a pig would be much less than lift a garage door. Maybe a small fan blowing over the motor would help with motor temps.

Yes, True. I think a heat shield to protect the electronics from the fire shouldn't be overlooked either. One of those aluminum for sale signs would make good, cheap material if a heat shield was needed.
