I just installed the Atlas 9 in my shop 2 weeks ago and it's great. Lifts my Dodge 2500 diesel pickup easily. I got mine from
Greg Smith It was $1648 picked up and no tax (Delaware)
Took me a day to install, by the way bolt down one post, connect the cross bar to the second post then drill and bolt down the second post. The directions make it sound like you should bolt down both posts then connect the cross bar.
You need a 12' ceiling. Mine is 11' 11 1/2 " and the bracket that holds the hydraulic hose just touches my ceiling
Good luck
Kevin
