Trusted By Commercial Drivers Across Missouri
Feedback from commercial truck drivers and owner-operators stranded in Southeast Missouri.(Sample testimonials shown below — verified client reviews will update periodically)
"Blew a coolant line at 1:30 AM on US-60 right outside Dexter. Called B&B and Shadow answered right away. He was on scene in 35 minutes with the right hose and clamps. Saved my load from missing receiver cutoff."
"Locked up air brake chamber on my trailer near Sikeston. The tow company quoted me $1,400 just to haul me to a yard. B&B showed up with a mobile truck, replaced the chamber, and had me rolling for a fraction of that."
"Severe engine derate code right before entering Missouri scale house. Shadow plugged in his diagnostic computer, identified a faulty DEF sensor, bypassed the derate safely, and saved me from an out-of-service citation."
