I built a 16x20 cabin up the Little Noatak River back in 04 and it has done well. I jacked and leveled it as needed normally every 2 years. It has been left alone for the pass few years and this was the summer for major work on the place.

Aug 1 was the date. We had major sagging on the SE corner so it not only required jacking but I had to shift 3 of the post/pads about 2 inches to the west. I reset 6 of the 9 posts and all 3 on the deck. The next time I need to level her I am going with cribs 24 x24 on the 4 corners
