A bit more than the typical Ford vs Chevy vs Ram (they are all good and have their own 'personalities' that either fits you or not)...but there are major differences between OEM vs after market brake controllers
First, how much money do you have invested in both your TV and trailer?...plus other valuation positions of life and limb. Personally will NOT skimp on this area...BRAKING
Since you do not have an OEM embedded brake controller, after market is the topic.
Add that, IMHO, most who complain about a P2/P3 did NOT have theirs dialed in well
My P3 leads the TV in braking. Meaning it tells the trailer brakes to start braking BEFORE my TV master cylinder ever develops any braking force. The trailer actually starts to slow down the whole setup before the TV's brakes engage.
Since both P2 and P3 are inertia based...once the above braking session starts...the accelerometer in them senses deceleration and will continue to tell the trailer brakes to engage.
Proportional in that it will vary the voltage to the trailer brakes in proportion to the accelerometer's sense of deceleration
Meanwhile, the TV's brake system gets into the game via my continual pressing of the brake pedal to develop MC pressure...which further decelerates...which the P2/P3 will sense even more deceleration to then increase the voltage to the trailer brakes
I can stop the whole setup WITHOUT ever engaging the TV's brakes just by keeping a light touch on the brake pedal without moving the MC rod to develop braking pressure
Key is setting up the TV brake pedal switch to snap over and turn on the TV brake lights BEFORE developing MC PSI. If plunger type (think door bell), it will be tough. Some of the newer TV's have a much better brake light switch
Good luck !

Thanks everyone for the info.
So I will get a Tekonsha proportional, what about this one, anyone using it? Primus IQ Trailer Brake Controller - 1 to 3 Axles - Proportional. Its a little less money than the P2 or P3.
Your opinions are valued.
