Windshield washer fluid

most of my problems have been pushing the red knob in and not hearing any air flowing in to the trailer.

Course, it helps to have the company change the dryer cartridges like they should be doing.

 

True. That's what I like about my company, they don't miss any of the preventative maintenance tasks. It's just cheaper in the long run, to do those relatively easy tasks on time and in a warm shop, rather then deal with the very costly delays and very expensive costs of road service elsewhere. Not a matter of if. A matter of when.
