Tow rig brake controller
My experience with electric trailer brakes is pretty limited. Will be installing a controller in my light duty truck to help slow down a loaded car hauler. Truck is an Explorer, with V8, tow pack, and class IV receiver. Trailer will be a tandem with brakes on single or both axles--yet to be purchased. Truck is currently wired for 4 pin. It's not wired for 7 pin or brake controller yet, so I have a blank slate.
I'm looking for a recommendation on a brake controller. Timed? Progressive? And if it has a single axis accelerometer, can I mount it vertically on the center console? Based on my reading so far, I think I want a progressive controller that can be mounted approx vertically, off the side of the center console--assuming such a creature exists. If you have feedback or recommendations on a specific model, please share. |
Why not the mechanical ones built into the tongue? I'm very limited on my trailer knowledge, but I do know about those. Just don't know any pros/cons of them.

If you have electric brakes on the trailer already get a TEKONSHA PRODIGY for the brake controller. After much research that is what I bought and it works great. It will compensate for being slightly off of level on the mounting. I have towed a dual-axle 20 foot loaded enclosed car hauler with it a few times already with no problem.
You will have to wire the truck for the 7-pin connector but it is not that big a deal. I did this myself last year on my Tundra because before 2003 they were not prewired for electric brakes. If you go to etrailer.com they have what you need and also have instructions on how to do the wiring. Their prices are pretty good too. You need the 7-pin connector, wiring, and a couple of self-resetting relays. For others, if your truck is already wired for a 7-pin brake connector (most of the new ones are) then just get the adapter plug for the Prodigy, mount it, and plug it in to your factory harness. Done. Electric trailer brakes are fantastic. |
Truck is currently wired for 4 pin. It's not wired for 7 pin or brake controller yet, so I have a blank slate. If you plan on going to VIR get a trailer with brakes on both axles, it's required in NC (and a lot of other states). This is NC's law. § 20‑124. Brakes. (e) Motor trucks and tractor‑trucks with semitrailers attached shall be capable of stopping on a dry, hard, approximately level highway free from loose material at a speed of 20 miles per hour within the following distances: Thirty feet with both hand and service brake applied simultaneously and 50 feet when either is applied separately, except that vehicles maintained and operated permanently for the transportation of property and which were registered in this or any other state or district prior to August, 1929, shall be capable of stopping on a dry, hard, approximately level highway free from loose material at a speed of 20 miles per hour within a distance of 50 feet with both hand and service brake applied simultaneously, and within a distance of 75 feet when either applied separately. (e1) Every motor truck and truck‑tractor with semitrailer attached, shall be equipped with brakes acting on all wheels, except trucks and truck‑tractors having three or more axles need not have brakes on the front wheels if manufactured prior to July 25, 1980. However, such trucks and truck‑tractors must be capable of complying with the performance requirements of G.S. 20‑124(e). (f) Every semitrailer, or trailer, or separate vehicle, attached by a drawbar or coupling to a towing vehicle, and having a gross weight of two tons, and all house trailers of 1,000 pounds gross weight or more, shall be equipped with brakes controlled or operated by the driver of the towing vehicle, which shall conform to the specifications set forth in subsection (e) of this section and shall be of a type approved by the Commissioner. I haven't started towing yet but I've already bought my controller and have a trailer on order. What I saw most controllers were okay with being at an angle but they still had to be in line with the direction of travel. So you could angle it up to see the display while driving. http://www.etrailer.com/Brake-Contro...sha/90195.html Was what I got. Likely overkill for my little Miata on an open trailer but it's a safety item. I'd rather have something better than I need than jackknife when my surge brakes don't work. |

My trailer has brakes on rear axle only, our other flatbed has them on both. The upside to both is that you won't flatspot the trailer tires as easily, but I've never noticed a stability problem with only 1 axle braked. Surge brakes SUCK. |
I also use that controller in my truck and bus. Works great, is predictable, and is super easy to wire up.
|
Another +1 for the prodigy. Pay a little more for one, cause it's an area you don't want to cheap out on, and it's a one time expense.

+1 on the Prodigy. I have one, came with the truck, works great. --Ian |
Thanks guys.
The truck is definitely not prewired for the trailer brake controller, but I can take care of the wiring. I will be picking up one of the Tekonsha controllers. Looks like it has to be mounted parallel to the direction of travel, which is too bad. Vertically off the side of the center console would have been a more convenient position (easier to reach and more visible) than under the dash, but so be it. If anyone has a trailer for sale in the Atlanta area, let me know. Preferably with brakes on both axles. |

Those yank controllers are so good I'm even rocking one in my tow rig here in Australia; Prodigy P3.
|
I had an original Prodigy, and now have a Prodigy 3 (P3). The original Pridigy, and P2 are still on the market (along side the P3. I'd go for the P3.
I've also towed with a Miata with a V8 Explorer. Suggest you look into a bigger truck for towing a car trailer. |
I like the original prodigy,

Besides I've put a lot into the Explorer within the year--new Michelins, new 4 wheel brakes (rotors, pads, rebuilt front calipers, wheel bearings), rear shocks and overload springs, class IV receiver, plus other normal maintenance. |
I am pulling my 20' enclosed car hauler with a 1/2 ton Tundra (V8) and although it is not ideal it works and I am within its towing capacity. Every time I calculate the ROI on selling the Tundra and getting a larger diesel it just does not make sense.

People in the US are kinda funny about towing with anything other than a 3/4 or 1 ton truck. Hell Tacomas are rated to handle 7500lbs if propely equipped. Given with a smaller tow vehicle, you have less room for error, but it can still be perfectly safe.

We bought the 2000 explorer in 2002 with 30k on it. It now has 205k. It's been a great truck, and I have the title. I have already installed overload springs in the back. I hate airbags and hope to not need them. I also plan on getting a weight distributing hitch. The truck is rated for the load I plan to pull, and should be ok with the weight distribution and trailer brakes so long as I don't need to cross mountains. |
I have never used the weight distribution hitch, but I know people who swear by them. I havn't taken the time to truly understand how they work, it just does. Kinda like a posi track on a plymouth.

+1 on TEKONSHA PRODIGY.
I've had one in my last two trucks, and I've given two as gifts to friends that already had brake controllers in their trucks, but changed them out for the Prodigy. |
The WDH works by limiting the downward angle of the trailer tongue, preventing the trailer from being able to push the rear of your vehicle down too far. The weight is still on the tow vehicle, but is better spread through the chassis instead of straight down on the rear. With more weight transferred to the front tires, you will have better control steering and braking.
