The individual components between the two kits are the same but the quantities are different since the part #AP302 was designed for triple axle trailers and the #AP202 is designed for tandem axle trailers.

Hi Stephen; it is the hitch and not the wiring that causes interference with the hands free liftgate. You will still be able to use this feature with the Curt Trailer Hitch Receiver #C64NR. Even if there is some interference, you won't loose the…
