The AF-1 is pretty easy to install yourself. The coach portion is super easy. You only have to cut a couple of pieces of metal to fashion a bracket for the quick connect on the rear of the coach and a mount for the air tank/relay valve...and bolt them on...drain the air tanks...assemble two tee air fittings...cut and push-to-connect the air lines...route the 1/4" line along the door side frame rail and secure it with cable ties...and go back and spray soapy water on the fittings to check for leaks after airing up the system.
It was my first time...so I sent a picture to SMI of the air lines on my coach with a wrap of red electrical tape where I intended to cut...they confirmed I picked the correct ones.
The vehicle end is very straight forward...but takes a bit of climbing around, and popping off trim to route the wiring for the LED coach notification light strip.
It's really too bad that people get turned off by the "warranty" issue...or listening to dealers that, in my opinion, haven't taken the time to see the merits...or simply want to sell what they have in stock.
I haven't found a single case of anyone regretting their decision to install the AF-1 supplemental braking system yet. Even on a Freightliner chassis.
Sorry for the rant. Really, they all perform the same function...and the most important thing is that you are happy with the braking system you chose.
