Hitch:
The industry standard for tongue weight is anywhere between nine percent and 14 percent of your gross trailer weight (GTW.)
Hitch Height
The top of the hitch ball should be at approximately 16” when the Aerovault is connected for a level tow. For most vehicles this means setting the top of the hitch ball between 18"-19" from the ground when the Aerovault is not connected.
The ball is 2-5/16” (~2-1/4”). According to eTrailer.com I should measure to the top of the inside of the hitch hole (13.25”) and to the bottom of the ball. Adjusting AeroVault’s number that’s 13.75” when connected and 15.75”-16.75” when not connected. So that’s a 2.5”-3.5” rise.
