Those rate increases exactly mirror the increased price of diesel. When Biden took office, diesel was $2.12/gallon where I am, today it is $4.15.
Shop rates for maintenance have also increased along those lines, as have the prices for tires.
We don’t eat the increases in our operating costs, any more than you do. Your flatbed company is charging a fair rate for that route out thru the gorge to Boise.
Actually, I do believe that the trucking company is being more than fair. I just wanted to give an example of freight increases.
