True enough, but you should also recall that there was no such thing as TVAL freight when Diane and I entered the business as drivers of fleet-owner straight trucks. We prospered without it before and can again.
It's not quite like buying equipment to haul wind generator blades. The only thing that makes a TVAL truck a TVAL truck is the datalogger, four temperature probes, trained drivers and documented maintenance.
If we remove the TVAL capabilities from our truck, the only noticable difference will be a new space in the dashboard where the datalogger used to sit. If we again start hauling TVAL freight, a new datalogger would go in that place.
There would also be lower maintanence costs and lower equipment leasing costs.
I have my old equipment at the house. It was mine to start with.
