How is etrailer Hitch Difficulty Scale Calculated

Question:

How is Installation Difficulty scored? Is 9 out of 10 easy or difficult? There is a claim here that 9 out of 10 is really difficult and that they should look for a hitch rated 2 out of 10 to be easier to install. What say you? Thanks!

Our hitch install difficulty scale numbers are based on the length of time it takes to install the hitch actually. So a 9 out of ten would take most people around 90 minutes.
