The lightest weight trailer
series on the market!


The integration of the Chaparral design into the Doonan manufacturing process has led to the development of the lightest weight trailer series in the market. The culmination of this is in Doonan’s newest product, the “Platinum”. This trailer combines the light weight bolt together deck of the Chaparral, with the light weight welded steel main beams of a Doonan, to create a combo (48’ x 102” flatbed) trailer that weighs less than 8,835 pounds.
