I bought a Snap On 2 ton floor jack about 35 years ago. It was actually made by Walker for Snap On, looking exactly the same as Walker jacks of the same era, only painted red with Snap On decals. It has served me well, still working perfectly.
I had to add another jack when I got the Ram 3500 in 2001. It weighs around 8,000 lbs or so. The options were another floor jack like the 2 ton Snap On only rated to lift more, which are large and cumbersome, or an air over hydraulic heavy duty jack.
I chose the latter. Rated at 22 tons it is a bit of overkill, but the design makes it easier to use in tight spaces. And it proved useful when I picked up a motor grader 15 years ago, which weighs in at 25,000 lbs.
