Well! I am limited by my garage. It is only 10' 8" inside and I am 6' 2" tall so I had to install it outside so it would go all the way up. I have a HOA here where i live and i built the garage to hide a trailer I had in the back yard. Little did they know the garage would be 1200 Square Ft. He He. But the trailer fits in it.... Also the single post lift cannot be seen over the fence when it is down. All other lifts you can see the posts...
