Toad / Tow Brakes

[drw907]

We will begin full timing within the next 6 months. Our motorhome is
a 1994 Bluebird BMC diesel pusher with a Spartan air brake chassis
(mountain master type class) , tow car is a 2005 Subaru Impreza WRX
wagon 5 speed.

I have done some net research, and have not made a final decison.

I do not want to have to add/remove any components inside the the tow
car to tow/drive. I want feedback inside the coach of what the toad
brakes are doing.

I will likely install myself, and while mechanically inclined, and I
have most tools, easier install is always nice - if it doesn't give
up too many features.

Thus far I am at:
SMI Air Force One
SMI Stay In Play Duo
US Gear Unified Tow Brake UTB-1000

I could use any advice/rational to help me decide,
Thanks,
Dan
