The steps mentioned below are what I took to mount the stabilizers to a 40×48″ trailer kit.
1) Before installing the stabilizers, I tipped the trailer on its side.
2) Using the existing hole on the frame, I mounted the jack and center punched the location for the second mounting hole location.
3) Drilled the holes for the second mounting.
4) Mount the four trailer stabilizing jacks.
Go back to step 3 or go to step 5 of the DIY camper plan instructions.
