"New" Maint schedule......again...

I don't know, but I would guess the A service is an idiot proof maintenance doublecheck to make sure the drivers are keeping up with air in the tires and making sure the fluids are topped off.
Technically we are supposed to get the truck and trailer inspected for all that stuff every time we stop at a terminal if the shop is open but sometimes there is no time to do that if the shop is busy and you have to keep rolling. The B service is the more important one that needs to be done to make the manufacturer happy and cannot be missed.

 

With Knight
Old Maint
A Service - 15k Miles = Grease fittings check truck of issues
B Service - 30k Miles = Oil change and Grease fittings and any other crap the driver has written up.

New Maint
10k Miles - Road ready, Make sure the truck is legal and the Driver have any "Unreported" damage
20k Miles - Grease fittings, check truck make sure is legal check for "Unreported" damage
30k Miles - Road ready, same as last road ready
40k Miles - Oil change and lube Grease fittings check truck for "Unreported" damage, fix driver remarks


The whole reason Knight changed it was to save a little cash on the oil side but also to catch drivers with "Unreported" damage, right now Knight has a huge problem with tlrs and truck getting tore up.. The problem is of there own doing as soon as they started hiring the CR England drop out's

 

Ah thanks that goes into more detail than what I was told.
Personally most of the trailers I've dropped and hooked have been in good shape minus where a forklift dinged the insides. I've only seen one get an OOS so far because of a cracked housing for the electric hook up.
