"They are on same board that Panther/Tri State/others used for auto industry. 95% of our loads are for top 3 auto makers"
It's that 95% of your loads being mostly NLMI freight that's the problem, especially in Detroit. It's not just Panther/Tri State or the other large-ish carriers that are the problem, it's the plethora of small mom and pop or single-vehicle operations consisting of former auto workers living in Detroit that bid low to get a lot of that freight. There are far more daily NLMI loads out of Detroit than Panther has vehicles in its entire fleet, for example, much less than the number of loads that Panther can get covered with available trucks in the area, so to try and blame low bidding on this or that carrier is an exercise in futility. More likely, your carrier's sales force would rather click, click, click the NLMI boards than pick up the phone or <gasp> go visit places to drum up new business. That's not a knock on your carrier, either, as much as it's a knock on most carriers, Meow Mix included.
But, I'm with Panther and I run an awful lot of stuff out of Detroit that is not NLMI or automotive freight.
