I was UE when it first started as pse ,We all drove junks ,check engine lights on head lights blinking fenders rattling ,I complained it it did no good what so ever. I spent more time broke down than driving some weeks ,I came to the conculsion they don't care so don't expect them to change as long as it is road worthy and is not a safety issue. I do the speed limit if I get passed by a cement mixer and a Amish buggy so be it I did the best I could with the equipment the gave me .When the T M asked what took me so long and they complain about 6 guys on dock waiting for freight. I just invite him to come with me .They can see everything your doing anyway.
When you do get a newer unit with low miles it's a problem child line haul does not want to deal with so they but it in the city to let the city operations absorb the cost of repairs .When you break down they will give you another junk if you go into a break with a city unit your leave with one, at least that's how it used to be
