We tow a Jeep Wrangler and use the SMI Stay and Play Duo brake system. It may require a more detailed install but once in you don't even know you're hooking your brakes up. One plug tail lights and brake system.
I liked the idea that it activates your power brakes, similar to to when the car is running and your driving it.
There are many good systems out there, you need to weigh what you want, how difficult or expensive the install, etc.
I will say one thing; The first trip we towed our Wrangler with the brake system installed it saved us an accident, I have no doubt. We were cruising at 45 mph in the left lane with our turn coming up in about a mile. All of a sudden a little red car in the center lane pulled in front of us and came to a complete stop quickly. She had decided she needed to make a left turn
I was all over our brakes, we stopped like maybe a foot from her rear bumper. From our coach I couldn't see her bumper or trunk, only the back window, we were that close!
I can completely confirm our brake system was working, it actually felt like the towed was pulling us back. Upon releasing our brakes when the event was over I could feel my towed brake disengage and let go of us.
I can't say no other system works as well but I can say ours works extremely well. At my fuel stop a mile up the road another RV pulled in, they were about 300 feet behind us, saw the entire incident, he told me there was no way I didn't eat that car alive.
Good luck with your decision,
Steve
