It is simply about supply and demand.
A private seller may inflate the price of a truck , not really caring if it sells , but a commercial retailer must move product to stay in business. Apparently the demand supports the prices we are currently seeing, while at the same time energy cost escalation and supply chain compromise is pinching supply.
I don’t like it more than anyone else , but I accept the unfortunate reality of it all , without thinking that there is some sort of price fixing conspiracy involved.
