Rack assemblies and methods of using

A rack assembly for supporting an item above a ground surface, the rack assembly comprising:

• an upper subassembly comprising an upper rod having an upper end and a lower end and at least four arms extending laterally at the upper end of the upper rod, at least two arms of the at least four arms defining a first arm unit and at least two arms of the at least four arms defining a second arm unit, the first arm unit being removable from the upper end of the lower rod, the second arm unit being permanently affixed to the upper end of the lower rod;
• a lower subassembly removably connectable to the upper subassembly, the lower subassembly comprising a lower rod having an upper end and a lower end, at least four stabilizing prongs at the lower end of the lower rod, and at least four beams that laterally extend from the lower rod adjacent the lower end thereof and offset the at least four stabilizing prongs from an axis of the lower rod, at least two beams of the at least four beams and at least two stabilizing prongs of the at least four stabilizing prongs defining a first stabilizing unit and at least two beams of the at least four beams and at least two stabilizing prongs of the at least four stabilizing prongs defining a second stabilizing unit, the first and second stabilizing units being rotatable relative to each other and relative to the lower rod;
• and
• means for removably connecting the lower end of the upper rod to the upper end of the lower rod to arrange the upper and lower rods coaxial with each other.
