Proportional Braking

A vast improvement over "on/off" systems, which brake at a single pre-set level, the Patriot 3 has a proportional design for equal braking. The actuator inside your towed car applies the brakes with the same intensity that you apply to them in your RV. If you slam on the RV's brakes in an emergency situation, the Patriot 3 engages your towed car's brakes with virtually the same intensity. If you press the RV's brakes just enough to slow a bit, your towed car's brakes are depressed just enough to slow it down, as well. The result is improved control, better stopping and less wear on both your vehicle's and RV's brakes.



BRK2019 Blue Ox Patriot 3 Proportional Braking System

Replaces BRK2010, BRK2012, and BRK2016

There is no easy way to actually review this, it is not like i am sitting back there watching it when i have to brake hard on my RV. I know that it works, it does engage brakes. The breakaway works. Two things to note/complain about. When driving, every now and again (maybe once a day), the controller will beep but have no indication of what it is erroring about. I assume connection wireless or power in the back perhaps, but really have no idea. They should fix it so that if any fault is indicated it displays for at least a few seconds, and that one can go back and see history. The other thing is sensitivity and force settings. The instructions have no information at all on how to actually gauge what is appropriate. The sensitivity i can see as I am driving, how easily it start applying force, so this i can adjust on a gut. But force? there is no way to test this. Every single person i talked to or seen videos just set it smack in the middle. In one sense i don't really want it to kick in unless i am braking fairly hard, and i want it to kick in pretty good when i do so, but i fear the delay in applying may make the actual action less helpful. I have only had to panic brake once, i drive a 37' class A, my rear wheels locked for a few seconds, back end started coming out. I really have no idea what the flat tow was doing or not, wish i had history from the system and videos etc. So all in all the product is okay, but it could be better. I dont know of any other system that is better.

I received my Patriot braking system with a damaged part. I contacted the manufacturer and they in turn contacted etrailer. Long story short, the damaged part was promptly replaced. I would do business with these folks again based on their fair treatment in my case.

This review is for E-Trailer. I ordered a complete dinghy towing set-up for the dinghy as a towbar came with the RV we purchased. I called E-Trailer and spoke with a very knowledgeable young lady and when I told her what I needed in layman’s terms she came up with what I would need to complete the dinghy preparation in order to safely tow it behind our RV. Everything they said it would do went just as the instructions directed. I ordered a Roadmaster Falcon 2 set up for the dinghy and they suggested a Blue Ox self contained braking system for the SUV itself. hey also suggested the complete wiring system and plug for the dinghy. To my amazement after the RV and dinghy were connected that also was as easy as they said it would be. Our first tow with the dinghy was great and the unhooking was also a very easy experience. This company was awesome to work with. Thank you for your knowledge and great products.

This has to be seated just right or it will default. We had it set as required and it moved slightly on a bumpy road and faulted. Where do you not eventually hit a bump. Then, you have to pull over to stop the coach and reset. This was exacerbated more because we also had to reconnect the battery to slightly move the seat. Then start all over again. We just think it should be more user friendly and not demand perfection to be able to work correctly. We have always used blue ox and this is the first product that performed less than expected. Most of the time we just disconnect and leave it in Place in the case of a safety check, which is especially disappointing.

I selected the Blue Ox Patriot 3 braking system because of the ease of use and the ability to move it to another vehicle if I needed to. Also there was no wiring needed in the towing vehicle. I test drove with the Jeep being towed and everything worked fine. I really liked all the information that the monitor displayed. The etrailer service was excellent and the shipping was quick.

Went well except for instructions installing baseplate for my 2017 Silverado. After grille removal was not close to the instructions. I [looked for installation videos for] 2018 model and instructions for grill and bumper removal was right.

Easy to install and set up. Towed across the US in 3 days and the wireless display saved the brakes on our Jeep (the unit bounced and tipped over after driving over large bumps). Double edged sword, the unit is really light and easy to take in/out but is so light that large road bumps can jostle it. Adjusting the feet on the base of the unit and driver's seat seemed to help.

Overall, the Blue Ox system has worked out great. I had read a lot of reviews, mostly positive, but some who had some difficulty with the installation, but in my case I had no real difficulty at all. The base plate lined up good, I did use a pry bar to spring it a bit, but nothing major. Ok, so this review if for the entire Blue Ox base plate, Blue Ox Alpha, Patriot II and Hopkings light kit package. I deviated a bit from the base plate installation procedure. I never used the vice grips, I simply installed the 5/8" bolts, leveled the plate and torqued them up after applying red Locktite. I was able to wedge/slip the spacer bars into position and then I drilled the frame using the base plate/spacer bar combination to keep the drill perfectly aligned. I did not have a 17/32 drill so I simply used a 1/2" drill to start each hole. I then swapped down to a 1/4" drill to punch through the frame and progressively drilled the hole larger until I got to the 1/2" bit. I have a Drill Doctor to keep my bits very sharp so they do not drift or wander. Great tool for your shop if you do not have one. I also drilled the hole toward the rear first. Once that was complete, I installed the rear most 1/2" bolt, Locktite and torqued that bolt. I then started a 1/2" hole using the base plate, swapped to the smaller bit and again progressively drill to 1/2" using the spacer as a guide and installed the front 1/2" bolt with Locktite and then torqued. I can see where if you installed the front bolt first, it would be difficult to reach the rear to get the nut started. I rechecked the torque on all the bolts once installed. Word of caution, the nuts have some "teeth" to bite into the frame when installed. These kind of nuts do not want to be tightened and loosened repeatedly. You want to install them once and go right to tightness. Less risk of breaking the wire that is welded to the nuts because the teeth are initially sharp and will bite into the frame. If you tighten and loosen these nuts the teeth get duller and will not grab very well. The purpose of the wire is only to align the nut with the bolt. I did slightly "kink" the wires on the bolts so the nuts started easily on the threads of the bolt. To refit the air dam underneath, I simply measured the distance between the left and right side of the base plate and transferred that dimension to the plastic dam. Rather than cut with a knife, I drilled a 1/2" hole in the plastic dam at the bottom end, used masking tape to mark my cut lines and then finished with a fine tooth jigsaw cutting 1/2" slots. Since the base plate is 1/4" thick the 1/2" slots give me a bit of play and look nice and even. I did not take photos yet, but if I can get back here I'll post a few of the finished product. Among the things I really like about this is how up tight and close the base plate connections are to my bumper. You really do not notice the base plate when you look at the front of the Jeep which to me gives it a nice clean look. I got a Patriot II remote braking system. It took me longer to route the "break away wire" and switch than to set up the remote control. The Hopkins brake light package was easy to install and directions were clear. Spent most of my time deciding how to route the wires from rear to front.

    According to Blue Ox the Blue Ox Patriot 3 Radio Frequency part # BRK2019 draws .50 amp (half an amp) when just plugged in. When activating the brakes it draws 1.50 amps so it will not drain the battery as long as you unplug if the vehicle will be sitting for a longer period of time.
