I went to the mental Olympics trying to figure out what the truck hitch height would be with two variables: a new third party hitch mounted some unknown distance below the factory hitch (the manufacturer of the hitch could not answer the question) and a complete suspension modification. The hitch was installed first and my best calculations went up in smoke as soon as the suspension project was completed.
I was way off on my guesstimate. I am glad nothing had been ordered to interface between the truck and the Hensley Arrow hitch.
Sometimes I just have to let things come together to get an answer.
