Since you have the brake controller harness your cost should be quite a bit less than what I paid.BTW my AS dealer said that was a good deal I got from U Haul.Congrats on your TV.
Thanks Ron - that's a great idea - I'll try them - our airstream dealer isn't close!

I tow with a 2018 Grand Cherokee and would only do so with a brake controller. I don’t think you would feel safe without it.

As far as i know every state requires trailer brakes on trailers as heavy as an AS. No brakes without a controller! This is basic towing info, the dealer should have known or told you he did not know. Misinformation is dangerous.

The "only" answer to that question is "YES, you require a brake controller"

I have a 2017 Jeep GC, and definitely use my brake controller. I set it so that Jeep and trailer stop evenly, ie both doing the work. Can feel it if it is out of sync and the Jeep does the stopping. Have to retune it occasionally. So yes, it is necessary.

Do I need an electronic brake controller with new 2018 Jeep Grand Cherokee?

And, as we have seen far too many times around the forums, depending on a dealer to know what they are talking about (or not talking about) can be hazardous.

Just points out the fact that you have to do your own research and gain full knowledge about your vehicle, towing setup and other subjects. You are generally in the best spot to have full knowledge, nay specialize in what you are driving and towing.

Dealers are usually best at selling stuff. I seriously doubt they even try to be experts on anything else. At least that’s my experience. Do your own “due diligence” research first.

Then you are ‘armed’ with knowledge, and in a better position to know what’s real and true. It takes effort, but it’s vital to being an “informed consumer” rather than a victim...or, as I cynically put it, “lawful prey”.

We use a Prodigy wireless controller with a handheld unit — you can put it anywhere. Sorry about the Jeep...I work for Toyota and the V6 4-Runner should easily tow a 23 — what did your dealer tell you?

Toyota's website shows 5000 lb max towing. Working for Toyota maybe you know otherwise... The gvwr on that airstream is 6000 with a 720 lb tongue weight. Bad idea...
The Jeep has a 7200 lb tow rating, plus a hundred more horsepower for those hills. Our old Grand Cherokee had the 4.7 v8, but the new one with the Hemi makes towing our 5500 lb Trade Winds effortless.
Fyi our progressive brake controller with wiring harness for our Jeep was very easy install, plugged right in under dash, took about 15 min

If your Jeep Grand Cherokee has a factory trailer brake control, use it. I'm towing a 2007 34SO (12K lbs.) with a 2011 Dodge RAM 3500 crew cab long bed dually. It was factory equipped with the ITBC, Integrated Trailer Brake Controller. I used it with my 1999 AS Excella with electric drum brakes and it was excellent. Now I use it with the 34SO with electric over hydraulic disc brakes. I replaced the OEM brake actuator on the AS with one made by CTS, formerly Carlisle. It works very good although newer TV's have a changeable option for the 2 different types of trailer brakes. Jeep is product of FCA, the same as my RAM, and the ITBC units are actually manufactured by a company who also manufactures aftermarket brake controllers. I've towed my AS in excess of 15k miles with zero problems.

Contact Tim from - they have vehicle specific wiring harnesses and brake controllers . Just installed their unit in my 2019 Tacoma. Quick & easy install after watching their installation videos.

We had a 2014 27' Eddie Bauer in the past and pulled this a time or two with our 2014 Jeep Grand Cherokee with the EcoDiesel. We had a brake controller added that was installed just below the fuel door button. Worked well for us with no leg interference.

No need to repeat the excellent and very consistent responses to your inquiry.

I have 125,000 mi on our 2014 Jeep GC EcoDiesel (identical towing specs compared with the hemi V8), over 50,000 miles of it towing our 2015 23FB FC. We use a Tekonsha Prodigy 3 and it was easy to install with the Jeep’s OE harness. Placement is the question. Though I chose to place it on the right side of the lower air bag cover (used stick on Velcro fastener which works great without drilling into the Jeep). I really like the photo of the left window-dash area placement. Reaching for manual control woukd be much easier on the dash.

Having traveled Seattle to NL and several other cross country trips through mountains, I’ve found it helpful to use the just manual control of the AS brakes when going down very steep grades while completely avoiding use of the Jeep brakes. That, coupled with using the paddle shifters to stay in lower gears makes the Jeep feel like a very secure experience.

During my recent oil change the Jeep brakes are only showing 50% remaining life on the pads. The AS brakes show similar life during my recent wheel bearing lube.

My Tundra did not have a built in controller (2015) but it did have the wiring harness. I bought the Tekonsha Prodigy 3, and it was a 15 minute install. The hardest part was mounting the bracket. (I like the Prodigy 3 a lot!!!)
I'm not saying all cars are prewired, but you can use Tekonsha's vehicle selector and it will tell you.

UPDATE: It looks like your 2018 Jeep GC is prewired.
You need a harness 3045-P to mate the controller to the
Jeep harness.

For my Tundra, I looked at YouTube videos to find how others did it. Easy-Peasy.

Here's one for Jeep 2014:

Yes...any tow vehicle needs a way to use the brakes that every Airstream is equipped with....The Jeep Dealer is full of not knowing what he is talking about.🥴
