    I'd be calling out another company... Whoever you got coming out is just having you throw money out the window essentially... Your spending money on the side of the road on stuff that doesn't need replacement...

    Your sitting in the truck on the side of 80 this entire weekend or you got yourself a hotel?

    Yep, if service relay valve is leaking when button is in recheck spring chambers for leaking seal. Your method of crimping or removing the service line at the chamber and releasing the park brake is spot on!

    If you have an adjustable wrench, a caging bolt, dime, or small piece of plasic we could probably get you off the road.

    Sitting in the cab, guarding my truck loaded with new vehicles.. )
    Other companies were even worse, never came over or never returned calls. It is a little village here, not much going on.

    I was going to do that, but a bit scared to drive without brakes in the mountains. Loaded, almost 80K

    You would still have brakes, just be short one parking brake.

    If I cage brake chambers on rear axles, I would still have service brakes working?

    Yes, but you would only need to cage leaking one if you do have a leaker.
