Well I wanted to report back after our 900+ mile trip. I must say this brake controller works well. It's surprising how much better it is with brakes...haha. The proportional braking is very smooth and feels a lot better that the on/off braking of other units I've used in the past. I'm not sure if this is how newer brake controllers work or if this is a Redarc feature. Got the correct harness while we were gone so I'll get that installed soon. Overall I'm very happy with the unit and how clean the install is (identical to the Mopar brake controller). Anyone doing some towing with their JL or JT I'd definitely recommend it.
