"Minimal at best". Most irritating is that for 2005/6 Ford removed the rear wheel well splash shields to save a buck and now on wet roads the wheels throw water, road oil, spilled chemicals etc. up through the seam under the lip of the bed rail and into the bed - with a shell on the back everything inside still gets wet. Once again Ford has found it acceptable to lower the overall quality to save about three dollars in plastic. I have to wonder what other corners were cut. I remember when car makers would make improvements every year. Shifting linkage is clunky and the 4 cylinder engine vibrates more than most. Also the bed does not 'fit' the width of the 2 door cab and looks awkward.
The price was right - but you get what you pay for.
Focus on providing an economical quality product and stop 'cheapening' existing ones by de-engineering them to save a buck. My personal improvement will be to buy Japanese again.
