Help, I can't get off my creeper

I have a symmetrical Gemini which seems to compare to Rotary. If I was buying another two post I would definitely get an asymmetrical one because with the front arms being shorter you can get smaller vehicles on easier with out having to push them back and forth to get the arms under them. Also with my dually it is hard to get out the door with the symmetrical lift. If you find a service station going out of business you may find a quality lift cheap. I bought a 4 post alignment lift out of the local Dodge dealer after tornado destroyed the building. Just some things to consider, Joe
