Its been over 12 years since I ran one. The model I used and the one I am getting have 5HP Honda motors, mounted on a tripod and have a water pump. Add a shoe box full of bits, anothew box of couplers, and a stack of drill stem pipes... all you would need is the PVC for the well liner and whatever the screen thing is called that goes in the bottom of the well.

The whole setup would fit in the back of a small pickup truck.

I learned how to drill on the 2 hour drive up to where I used it many years ago. took us 12 hours to drill a 2 inch well, ream it to 3 inch, then ream it to 4 inch. That was a 33 foot well thru granite.
