Claim 24:
25. A modular wheel and suspension assembly, configured to be attached to a load, comprising:
a suspension arm comprising a linkage end and a rotation end, and further comprising an attachment point, an actuation point, configured to be operably connected to an actuator, and a pivot point that are arranged on the suspension arm between the linkage end and the rotation end, wherein the attachment point is below the actuation point on the suspension arm and is utilized to rotatably attach the suspension arm to the load;
a suspension mechanism supported on the suspension arm;
a pivot arm rotatably attached to the suspension arm at the pivot point and comprising a suspension mount, wherein the suspension mount is above the pivot point and operably engages with the suspension mechanism and an axle bore, configured to support a wheel; and

a rotary tongue comprising,
a tongue, configured to be attached to a vehicle,
a rotary bracket attached to the tongue,
a tongue lever comprising a rotary end that is attached to the rotary bracket and a stabilizer end, and
a stabilizer arm operably attached between the stabilizer end of the tongue lever and the suspension arm,

such that, when the actuator exerts a force on the actuation point, the suspension arm rotates toward the pivot arm, thereby engaging the suspension mechanism against the suspension mount to push the wheel toward ground level, which simultaneously raises the load attached at the attachment point and pulls the stabilizer end toward the suspension arm, thereby lowering the tongue to a position for towing.
