Ben, it does all figure in, everything you stated. Most of us have shown our Trailers brand and model in our sigs... though the tires are a different story.I've not towed my heavy load enough to determine if my braking is "lacking". I have IBC set on heavy electric and "10" level. I AM concerned about report outs on this forum AND the Cummins forum about the OEM IBC, afraid to naively believe that mine is working flawlessly....or is it?...Need to do some more testing...though...crawling along at 15 mph, manually actuating my brake controller, tires do lock up......Got some thinking to do..My unit is a 3 axle, electric brake set up at 44' 7" long and a GVW of 20K, loaded to a little over 18K now. As stated, all towing in the mountains and no issues with trying to brake speed of combo...BUT, enough conversation to have me
'pondering", "what if?...."
On edit: I can get P3 and the pig tail connector for the 2015-2016 Ram for $129 total.

Pull the emergency brake on your trailer and read the voltage (I prefer to read the overall current and individual brake current). With a triple axle you should read 11.5-12v or close to 18a of overall current (3a per brake). Assuming your trailer's overall braking system is working properly, this establishes a good baseline.
Adjust the Ram OEM IBC's gain to 10 and trailer type to heavy electric with hydraulics. Manually apply maximum braking with the IBC slider on the dash. Take the same readings. If they're the same or very close, you probably won't gain additional braking with the P3. If it's less, the the bigger the difference, the more improvement you'll gain with the P3.
On my trailer I obtained 11.7v and 12.4a when I pulled the emergency brake. I could only obtain 8v, 8.5a (double axle with 4 brakes) with the Ram OEM IBC set to gain set to 10 and heavy electric with hydraulics. With the P3 I obtain 11.5v and 12.0a with significantly improved realworld braking vs. the Ram OEM IBC's 8v, 8.5a.
YMMV.
That was pretty much what I was going to do to figure where I am..BUT, why did you recommend electric over hydraulic? My brakes are just electric...I was going to use my heavy electric mode set to 10. and use clamp on amp meter/multi-meter.

My TH is at my camp in WV, and I won't be there till Memorial Day weekend..Will check and report back, of course, BEFORE I order a new brake controller.
