Various embodiments, aspects and features of the present invention encompass a system and method for an adjustable chassis system (“ACS”) that may be removably fixed to a payload object so that transport of the object across rough or uneven terrain is made less burdensome. Notably, some embodiments of an ACS may be integral to a given payload object. Certain embodiments of an adjustable chassis system advantageously do not include axles, yet may be raised or lowered to adjust ground clearance of the chassis and payload object. Moreover, certain embodiments of an ACS may be easily disassembled or collapsed for compact storage. Yet another advantage of certain ACS embodiments is that, by virtue of the independent side-to-side height adjustment, a payload object carried by the ACS may serve as a level seat or work surface over inclined or uneven ground.
