You opened up a can of worms on that question...been discussed a bunch on here..lots of opinions...its really all in how you plan to use it..I prefer the 2 post..easy access to all tire and suspension work as well as trans..rear..etc..can also be used to remove cabs, beds and such..I've even used mine to unload my trailer..I got mine from greg smith equipment..its a atlas 10k..extra wide , extra tall..very hapy with it..one of the best investments I've added to my shop..
