Happyjack or Torklift

I installed Torklift tie downs on my 2014 Chev dually in July. You need some sockets and a torque wrench to tighten the bolts to spec. that they give you on the installation sheet. My install was a little messy as the undercoating got squished out as I tightened everything up, but if you live in an area where undercoating isn't necessary you should be good to go. Depending on your application E-trailer has many install videos on the website, so you aren't going in blind. I found the video for my install 2 months after I put the tie downs on.:S
Good luck in your decision.
