Sold my old reliable bowtie dually and picked up a '99 Dodge dually with a Cummins

My old controller was a cheap piece of $#!+. Would always be jerking the trailer around with no real fine tuning capabilities the brakes were either ON or OFF.

Pulling a 26' Tag with a total of 9,000# max including the trailer.

What do you use and how do you like it.
Looking at the Tekonsha P2 & P3's, have you used them? Your thoughts please.

Thanks, Greg
