I cross Indiana on a regular basis. The manufacture lots are full of new trailers waiting for delivery to retail lots. Could be, they are ALL waiting for that mysterious part sitting on a container ship. However, chances are they are having trouble getting them shipped to the individual dealers.
One ad on the Indiana Turnpike reads:
150-180cpm

Cut that ONE WAY FREIGHT in half, that immediately brings the trip down to 90cpm. After expenses, they have to be down to about 40-45cpm. Deduct what Uncle Sam and all his brothers and cousins want...not much going into that transporters pocket.
I know I wouldn't be willing to sleep across the backseat of a pickup for the amount they are taking home. I like the creature comforts of my 389 Peterbuilt Fitgerald Glider.
