Abstract
The recreational vehicle trailer chassis includes two main frame rails running front to back with a series of perpendicular connecting main cross-members to form a structural configuration increasing the torsional rigidity of the frame. The main floor and support framing has a front and rear living area generally divided by the direction of structural trusses. Above the rear and middle main frame rails is the rear and middle floor framing formed with a plurality of frame members. Between the rear and middle main frame rails and below the rear and middle main floor support framing are structural web beam trusses perpendicular to the main frame rails along with vertical support columns that connect the lower main frame to the rear and middle living area floor framing further increasing structural torsional rigidity. Above the forward main frame rails and vertical support columns is the front floor framing with a plurality of frame members along with structural web beam trusses running parallel with the forward living area floor. Outward from the main frame rails and vertical floor support columns is the front to back side saddle framing to allow access to the basement area internally…
