I have a new-to-me 2010 Tahoe that is pre-wired for a trailer brake controller, and the previous owner must have had one as there is already a bracket under the dash with a connector present. We are looking for a travel trailer and need a brake controller. Any recommendations or education the brain trust can provide? Are some better than others?

Tekonsha. Should be plug and play. My current truck has a built in controller, but all previous trucks I installed the Tekonsha.

+1 on the Tekonsha.

Plug it in. Drive.

No dicking around leveling it or running wires.

I have a Tekonsha on my FJ Cruiser for use with my travel trailer. Have no complaints or issues with it.

Yep......Tekonsha!

I'm sensing a trend...

Another vote for Tekonsha
I've had a Tekonsha Prodigy (what I think they now call a P2) in my 2006 Duramax since new. It has been absolutely trouble free.

Again, another vote for Tekonsha. I use a P3 in my 2003 GMC 2500HD. Smooth as silk braking.

While I agree on the brand recommendation, there are a number of options on which model and they vary a lot in price. What are you towing? Then we can narrow the choices.

Guess I’ll be the contrarian. I had a Tekonsha P3. It worked fine but my knee kept banging it. A problem in my Frontier may not be in your vehicle. So now this one is in

It’s small and unobtrusive and works just fine. Towed a 4000 lb travel trailer over 12,000 miles so far

Getting unanimous....Tekonosha is one of the best and priced pretty reasonable. It's what I use.

Wait a minute. It's Tekonosha's fault that your knee bangs it?

Well, I was going to mention Tekonsha from my experience using it while
pulling a car trailer, but it appears that I'm late to the party.

We bought a used 2013 GMC Sierra half ton which I occasionally use to pull a car hauler. The car hauler has twin axles and brakes on all four wheels. There was no plug in on the truck but I bought a Tekonsha controller and spent an hour hooking it up. I could do the next one in fifteen minutes now that I know what I am doing. The Tekonsha has been first rate! I've trailered all my driving life (55 years) and it is the best one yet.

Don’t mount it in front of your knee. They hurt in a vehicle collision.

I have a tekonsha voyager sitting on my workbench. PM me Your address and I’ll send it to you. It has A Nissan harness attached to it, as I towed with a my Pathfinder. It worked for a dual-axle, single brake trailer towing a race car. You would need to verify the harness, which might need to be replaced for your vehicle.
