    Agree if, it is "my" (regular) trailer and I adjust my own brakes.

    Winner.
    There are some trailers, like the stretch trailers and the beam trailers that you can’t even get underneath to hook up without the trolley valve.

    Is there any other way. I do not drive trucks without my personal attention to details. No short cuts.

    There is no other way to fully charge the air system on a set of doubles so you can check for air all the way through to the back on both sides, than with the trolley valve.

    If it is your truck and someone else's trailer, you only use the trolley valve. Amazing how long your brakes will last.

    Cool, in difficult times. Gotta make it where you can, inconvenient or not.

    If the parking spring brakes on a trailer work properly, doesn't that mean that the service brakes on the trailer work properly?

    Till you have a trailer that won't. You have more brake force on the service side than parking.

    What the heck is a stretch trailer? Is that one of those trailers where the ceiling of the trailer is made out of canvas or some type of cloth?
