A drop deck trailer frame includes a front section having a first upper surface, a rear section having a second upper surface lower than the first upper surface, and an improved connection between the front and rear sections which tends to reduce cracking which commonly occurs in drop deck trailer frames due to the stresses in the region of the connection. The connection preferably includes a semicircular weld. In addition, heat treated bent flanges are typically used to provide additional strength. Fasteners such as bolts are also typically used to connect various flanges.
