I've worked with 2 post in ground, 3 post in ground, 65,000 lb cantilever, 2 post above ground and 2 post side by side in ground. My favorite to date is the 2 post side by side in ground. Takes up less space and I can drive over them if I need to. I had to price the 2 post side by side in ground once. Installed for the 10,000 lb Rotary was $2500. Something to think about is you are going to cut concrete anyway. I'll try to remember to take some pictures today.
BTW, drive over is important in my shop as I am 6 bays, 12 doors, almost all drive through. Two aren't drive through as I made them machine/storage/fabricating areas.
