I have max couplers on all three of my trailers and love it. I had an early one without the lip to catch the trailer side inside the jeep side and it made it a pain to reattach the trailer. The new model with the lip is super easy. I know there was a thread somewhere in here about their max coupler wearing out, but I have never had an issue. Probably 4-5 thousand trailer miles (including the Rubicon trail a few times) with no issues. and of course super quiet as there is NO play in the connection.
