madmaxx- lol, you're correct.
Very good safety questions, and I will try to ease your concerns.
A 4" slab with either rebar or the cattle fencing, is just fine.
Most residential or commercial foundations are strong enough to support a MaxJax lift. The minimum requirements is 2500-3000 PSI 4" thick concrete.
Think of it this way, if a loaded concrete truck, or like for me, having a dump truck with a full load of dirt or compost every spring, back up in my driveway and not crack the concrete. I'm not even concerned with the heavy weight of the delivery truck, with my lift in it and I'm sure he will have other products in the truck for other deliveries. The company has tested this system many ways, before marketing it.
Like I mentioned, my friend that has the mechanic shop, all of his are two post's. Now, they are the larger capacity for very heavy vehicles but again, they are two post not four.

I also want to say that I am not, a dealer. When I believe in a product, I'll voice my opinion, good or bad. I use the same forethought when buying different products for our sprint car. Proof is in the pudding.
