If you have your mind set on a full lift, you probably won't get much satisfaction from the QuickJack.
It is what I will be using to install my Welter P Stealth. I roll a Kobalt creeper through there with no problem. If I need more room, I take to max heighth. Using the QuickJack to get under the wife's Veloster. Never gonna have a muffler shop here or a two poster lift. So, the QuickJack is my easy way up. And should I ever need a portable lift, got it, providing there is an electrical outlet.
And that's all I got to say about that...
