Not entirely true. The $35 per week does cover any repair or replacement, which is no small benefit as these things are very expensive to repair.That $35 includes the services that you get also, and the replacement if need be.....so you would still be paying the carrier for the services they provide.
Then again, it ain't my QC.
The "services" of which you speak all directly benefit the carrier, not the contractor, and any services that benefit the driver can be done cheaper by other means. The only way it benefits the driver is the QC allows the driver to better operate within the carrier's system. But there are no benefits to the driver that don't first and foremost benefit the carrier.
