I don't know if this is a tech tip or what but I bought one of these and have used it and I think it is worth sharing.
I bought a new truck and it didn't have a trailer brake controller installed. I wasn't sure if I liked the truck and I was going to keep it so I was hesitant to spent good money on a trailer brake controller (again like I do on every single vehicle I seem to buy). Then I saw this unit from Curt.
I was skeptical and I worried about not being able to see it all the time. I used it last week for the first time and I can say it worked great. You can set it up and then forget about it or you can keep the app opened and use the manual brake button. You can also buy a separate button t activate the brakes manually if you don't want to have your phone out. The best parts for me is;
1- Zero wiring (if you have a 7 pin trailer wiring set up). I suspect you could run it on a 4 pin with an adapter and that would work fine too.
2- I can move it from vehicle to vehicle and I change vehicles regularly.
3- It saves 5 profiles so if you tow multiple trailers you can save them by name and not have to adjust settings whenever you switch trailers.
