Problem we have here, this seems to be a fairly small regional analysis. Maybe Ohio, West Virginia, North Carolina. Probably not a real good view of the overall picture.
A number of small Carriers are in fact regional(maybe a half dozen states) and don't haul that "really" time sensitive freight. Some do. Experienced equipment, if, maintained well, will in my experience, yield less actual "down time" than the neat newer equipment, with all the bells and whistles, sensors, etc. that constantly fail. I will agree the shadows from former Carriers is not acceptable. My spin is, if the owner don't take the time or, make the effort to clean those things up, then they won't take the time, or, make the effort to do anything else right either. So, i'd just let them keep floating.
As far as "shooting the messenger" go's, I wouldn't even consider authoring something that I got from such a small sample, or, second hand truck stop BS, from people that really aren't that observant at all.
BTW. It would be such a waste to open a whole six-pack. I personnaly do mine, one bottle at a time.
