Torn air chute

And if you add a pressure gauge
for estimating trailer weight and also added the air assist slide lock, you really don't want the bags to dump when you need to unlock the slide pins.

Waiting on the bag system to stabilize after re inflating, makes checking pressure more problematic then it needs to be.

HIGHLY recommended both a pressure gauge and air slide lock system [rather then the mechanical pull arm setup]

 

I just hold my brake pedal for a few seconds after I bump the dock and set my trailer brakes.

 

Our chutes can let air out from the half way point back. Even if the outlet of the chute was pinched shut at the very back, forced air could still migrate out and down due to the porosity of the back half of the chute. This is a worthwhile option IMO.
