Anyone using a GoJack to position aircraft in hangar?

Anyone have any experience of using a GoJak or equivalent to move/position an aircraft in a hangar (eg to give more space for other aircraft to fit in hangar)?
Also, which model GoJak? There is a model aimed at aircraft use (GoJak 4100 -

Is a specific aircraft model needed, or can you use tye car oriented GoJak 4500?

I have often wondered if they would fit under a standard RV wheel pant. I just found they need 3-1/2" of clearance.
