As others have said, too much crap in the side box. Had one where i picked up abandoned rig. There was this big tool box that would bump against the discharge handle every time i hit a pothole. I know this because you could hear it discharge every time and it took me a bit to find a safe place to pull over. That was one HELL of a mess. Had another where my oil jug pushed up against it and the pin pushed through that thin metal over time and it discharged into my face while i was rummageing for a bottle of wiper fluid. I now replace the blasted thing yearly.
The first one wasnt my truck i was just getting it from a dude that abandoned it. The second one there wasnt another place. No room by the seat since i had my pto controls in the way. And the other side had all my APU crap crammed into it so i only had so much room to play with. I did eventially get a storage box on the side. But eh. You works with what you got.
SO what happened to the safety tie wrap? Every one I buy has one, it takes a little bit of force to remove it. Do you know what happens when one is discharged in a closed space? This ... I've had a couple of drivers quit, and they let loose a fire extinguisher inside the cab/sleeper, which made a mess. As for the tank being washed out, you mean there wasn't anywhere else to do that but Houston? Just asking for a friend.
revert back to hand signals. You seen it was out, your on way to fix it, using the legal hand signals as backup.
Also he said it was a crucial light being my turn signal and that if he had let me go and I got into an accident it'd be all on him.
