I have been dealing with a specific trucking company for 15 years.
I use them to do one specific haul for me of lumber. Basically, the greater Portland, OR area to the Boise valley. I have done this haul hundreds of times.
Just a couple years ago the rate was $1250. Then it went to $1300. About a year ago it went to $1400. Six months ago it went up to $1600. Yesterday, they sent me a new rate sheet starting in mid February the rate will be $2000.
Some of this has to do with consolidation plus the fact that Boise is one of the fastest growing markets in the USA currently. More demand, less trucking companies.
Do the math on the above figures. Each time there has been an increase I have to pass that cost along to the customer buying the lumber. Sometimes, I get caught estimating the freight cost at the lower amount and have to pay more AFTER I took the order, and I have to eat the extra cost.
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.
