Receiver = the part bolted to the TV's rear end. Most likely the frame and if a
CUV, the sheetmetal body panel 'back there'
Draw bar = the metal piece that goes 'into' the receiver and is held by a 'pin'
that goes through the holes of the receiver and the draw bar inside the receiver
'pin tube'. The draw bar is 'half' of the WD hitch. If no WD Hitch, then the
draw bar has the ball bolted directly to it. Basically the part that has the ball
bolted to it...on some WD Hitch's, the ball is farther back towards the trailer.
Like the HA and the like
Hitch = the setup that marries the trailer to the TV. Consists of the above draw
bar that has the ball and the other 'half' is the bars (round, trunnion, etc).
Just the draw bar with the ball bolted to it, will weigh in the 20-50 lb range
Dependent on it's rating
WD Hitch setups can weigh from 100-to several hundred pounds
As to where the weight goes...it gets complicated and mainly to do what type
(architecture) of hitch system
