I have been getting by with a bottle jack on my Dakota, and would like a floor jack...but the problem is I have a not so good back. The shops I've worked in have had floor jacks up to 10 ton and I love that sturdy feeling they give when lifting equipment, but for occasional use at home I can't see going with even a 3 ton cause the area I park my truck at is separate from where my tools are kept, which means I would have to carry the jack...and after going through one back surgery I don't plan on doing any heavy lifting at home if I don't have to. So from what I have read on here, either I have to go with an aluminium jack or down size to a 2 ton floor jack. I am thinking a 2 ton would be plenty for my use, but the only thing that comes to mind is the small base they have. Are these 2 ton jacks stable enough when lifting? I am more of a buy once cry once kind of person on quality, but from what I see even the nice 2 ton jacks are almost 100 pounds. Are the aluminium jacks trustworthy? What back friendly options do you guys use?
