The single post is certainly an intriguing option. I was looking at them abt 6 years ago but the thought driving over the bottom support "leg" made me a bit nervous. I opted for a Bendpack 4 post, no bolting to floor required. With the optional large casters I can roll it outside or place it at any angle I may choose in the garage. They have lots of interesting models.... check them out online. I have been very happy with them from delivery, to set up, to service. Best of luck with your search.... Having any type of lift that will suit your intended purpose is a bonus!
