Cool garage!I have an XP-10CX. Like livewire said it is 145" tall. I have a 13' 1" ceiling and I have a good foot above it. I absolutely love this lift (My back and knees love it as well ) I mostly work on aircooled vw racecars, but have had my wife's minivan and my 97 Chevy Crewcab Dually up it with no problems. Glad I got the "X" as it is a foot wider. Big difference.
I dunno, but I can lay a level across from arm to arm and it's right on the money now. 
I'm across the Chesapeake Bay Bridge on the eastern shore. About 20 minutes past the bridge. I used to work in the Lanham/New Carrollton area when I had my shop. So, you got your lift delivered and up already? That was quick. Did the installation go smoothly?
