I purchased this kit to align my 2010 F-250 SRW short pickup with a 14,000lb fifth wheel. More than enough material was provided to set it up the way I wanted and place it where I wanted it. Installing the bags themselves was very easy. However, due to the versatility of this set, many additional pieces are included. More detailed assembly instructions could have been given to describe the use of mix and match style screws. The wiring from the battery and the relay could be made much shorter. Overall I am satisfied with this kit. I still have to test with trailer weight.
