Drop hitch height?

[kf9yr]

I'm now in the same position as the original poster.  Just bought a 2018 Silverado 1500 LT 4x4 with 18" tires all factory no lift or leveling.  The top of the receiver is 20" off the ground (and obviously the bottom of the receiver is 18").   I want to go with the weigh-safe hitch.  I'm just stuck deciding between the 4" drop and the 6" drop.  Tow a 18' car hauler with a compact tractor on it and a 18' ski boat.  A 4" drop is what I have in an old rusted hitch ball now and I think that's all I need.  That said, I always prefer flexibility or future potential if available without any huge current compromises.  In the video below a 6" drop is attached to stock 2015 Sierra 1500 and at 2:00 he measures his receiver top height at 19.75" off the ground so basically same as mine.  He mentions at this point also that the bottom of the drop is 10.5" off the ground and he should probably have gone with the 4" drop.  I like the extra 2" of flexibility assuming 10.5" off the ground wouldn't wind up bottoming out on a pitched driveway that changes pitch from a level street or something like that.    Decisions.....
  
 

I have one of those with the 2.5 inch shank. It works really well for me because I have a couple trailers with different heights and it’s quick and easy to adjust.
