Abstract: A method for stacking trailers is described. Firstly, position a first trailer on a skid assembly having an upper support frame that overlies a top of the first trailer. The upper support frame has a first end and a second end. Secondly, secure a first end of a tow line to an end of a skid assembly for a second trailer. The tow line is extended over the upper support frame from the first end across to the second end and then a second end of the tow line is secured to a winch. Thirdly, activate the winch to raise the skid assembly of the second trailer to the height of upper support frame and then draw the skid assembly of the second trailer from the first end of the upper support frame across the upper support frame until the end of the skid assembly of the second trailer to which the tow line is attached is positioned at the second end of the upper support frame.
