Annie, I have not checked out the price of the 4900 - however we have spec'd put the class 8 9200, the price for the truck has come in considerably lower than the heavy duty Freightliner, and even beat the price of the FL106. Carl Sommer at Wise International Ft Wayne IN has the specs or feel free to email me.
BTW - the truck is speced out for weight, alum where it made sense, C10 Cat due to the lightness of the engine and price, etc. The cost could be cut considerably if you are willing to sacrifice the weight.
