SMI Air Force One Brake system?? or other brake systems?

Went from an SMI Stay-n-Play to an AF 1. What a difference, I am kicking myself for not doing that in the first place. The proportional braking is unbelievable.

Had US Gear from 2002 until 2015 on a Jeep Liberty (towed over 120,000 miles) with no problems. Loved it!! Bought a 2012 Jeep liberty in 2015 and could not find a new US Gear setup. I investigated many other brake systems but ended up going with the new version of the US gear system made by the inventor of original US Gear system. It is called SmartBrake and is relatively simple to install (and would be easy to move to another vehicle. It uses a standard brake controller which gives you full control of the towed vehicle. The unit is contained in one box which I installed in the engine compartment (drivers side). Made for a very clean setup. I have only towed about 3000 miles so far but I am very happy with the system.

Just installed the AF-1 in my jeep wrangler. Connecting the Jeep take two minutes, same as disconncting. Braking works great. Exiting from the highway to a rest stop on the way to Florida, went from going 65 to a 15 mile an hour turn to get in. First time I ever had to stop that quick. Did not even notice a difference with the toad!

Brian.....I don't think you can go wrong with either AF1 or M&G. I would have bought the M&G unit, but their wasn't room for the unit on the first vehicle I installed a brake system on. I've moved the AF1 unit to three different trucks over the years. With M&G, I believe you can exchange the toad portion of the unit (at a cost) when you change vehicles, if it will fit. Again, both good systems, but the AF1 might be a little more interchangeable if you change vehicles in the future. If your future vehicle doesn't have room for the M&G unit, you would have to start all over.

SMI has recently improved the Air Force One unit by making the toad controller smaller and incorporating the brake away tank into the controller. They also improved the unit that mounts to the MH. In the past, it was just a line tapped into a brake can. The DOT had issues with this and so did Freightliner. The new unit uses more safety features if an air line should break.

Brian,

We have had both the M & G braking system and now the SMI AF-One. Both are very similar.

If I understand correctly, the M & G has a pump on the master cyliner, the AF-One installs a hook to the brake pedal through the firewall. Works perfectly.

The reason why we went with the AF-One on the new Honda is that the engine compartment had changed from our 2007 Honda. The M & G could have been installed on the 2013 Honda but would have needed 8 hrs. of labor vs. a couple of hours with the AF-One.

Both work well.

MM.

We went from an EvenBrake to the AirForce One. It really makes it difference. When I press the brakes on my coach the toad breaks come on immediately in the same amount of pressure. A side benefit is the engine braking doesn't engage the toad brakes like it does on other systems. With my DP coach the brake lights come on when the engine brake is active. This will activate most proportional toad braking systems causing premature brake wear on the toad brakes. The AirForce One system does not suffer from this problem.

Not AF One, but I have the SMI Stay-n-play and I'm very happy with it.
