A utility truck including a boom with telescoping segments, and pistons connected to two pivot points on a base bracket of the boom, for raising and lowering the boom. The truck includes first and second sensors each mounted at different locations on the extension bracket. Both sensors monitor deformations of the extension bracket. An average of measurements of the sensors provide a first load value representative of an axial deflection of the boom. A difference between the measurements of the sensors provide a second load value representative of a lateral deflection of the boom. A control system receives signals from the sensors and controls power delivered to the pistons based on the received signals.
