ABSTRACT:
A trailer apparatus having a perimeter frame with a front, rear and intermediate portion thereof includes a trailer hitch attached to the front of the perimeter frame for permitting it to be attached to a towing vehicle. Wheels are rotatably attached to the perimeter frame and have axle-supporting structures passing between the left and right side aligned wheels. The tilting bed is pivotally attached at a point above and midway between the rotational axes of the axles, in the case of a tandem wheel arrangement having two wheels on each side thereof, or immediately above the axle on a trailer having just one wheel on each side thereof. By having the tilting bed pivotally connected to a perimeter frame at this point, the perimeter frame of the trailer will not have a tendency to tip during the loading process.
