A suspension system (56, 56A, 56B) comprising: a gas spring and gas damper assembly (74B; AS1; AS2) securable between an associated sprung mass (36; 44; 52; 58) and an associated unsprung mass, said assembly (74B; AS1; AS2) adapted to operate in a first condition in which said assembly (74B; AS1; AS2) provides spring and damping functionality across a first range of travel when the associated unsprung mass is in a deployed position and a second condition in which said assembly (74B; AS1; AS2) provides actuator functionality with a second range of travel that is substantially less than said first range of travel, said actuator functionality operative to retract the associated unsprung mass into a storage position and retain the associated unsprung mass in the storage position for an indeterminate period of time; a pressurized gas system in fluid communication with said assembly (74B; AS1; AS2); and, a control system in communication with at least one of said assembly (74B; AS1; AS2) and said pressurized gas system, said control system operative to: receive a signal initiating a transition of said assembly (74B; AS1; AS2) from said first condition to said second condition; actuate one or more control devices operatively associated with at least one of said assembly (74B; AS1; AS2) and said pressurized gas system to transfer pressurized gas within said assembly (74B; AS1; AS2) to transition said assembly (74B; AS1; AS2) from said first condition to said second condition and thereby retract the associated unsprung mass into the storage position and retain the associated unsprung mass in the storage position; maintain said assembly (74B; AS1; AS2) in said second condition for an indeterminate period of time; receive a signal initiating a transition of said assembly (74B; AS1; AS2) from said second condition to said first condition; and, actuate one or more control devices operatively associated with at least one of said assembly (74B; AS1; AS2) and said pressurized gas system to transfer pressurized gas within said assembly (74B; AS1; AS2) to transition said assembly (74B; AS1; AS2) from said second condition to said first condition and thereby extend the associated unsprung mass into the deployed position. a gas spring and gas damper assembly (74B;

AS1; AS2) from said first condition to said second condition; actuate one or more control devices operatively associated with at least one of said assembly (74B; AS1; AS2) and said pressurized gas system to transfer pressurized gas within said assembly (74B; AS1; AS2) to transition said assembly (74B; AS1; AS2) from said first condition to said second condition and thereby retract the associated unsprung mass into the storage position and retain the associated unsprung mass in the storage position; maintain said assembly (74B; AS1; AS2) in said second condition for an indeterminate period of time; receive a signal initiating a transition of said assembly (74B; AS1; AS2) from said second condition to said first condition;
