Kyle is the owner, He does sales, service and installs. He did my Challenger 4 post install.
You better check the 4 post lift requirements for spacing. My Quality 4 post that is going in about a week from now needed 11' x 22' to install. If you garage is 22'x28' your floor area will be 20'x26' because of the frostwall/footing.
My setup is 28x28 with half storage loft on the right side, left side open for a 4 post lift.
