ABSTRACT:
The disclosure is generally directed toward vehicle support systems. In one embodiment of the invention, first and second support assemblies can be pivotally coupled to a base. A control mechanism can couple the first and second support assemblies together and be configured to control pivotal movement of the support assemblies between spread and stowed positions. In another embodiment, first and second support assemblies can be pivotally coupled to a base and to first and second wheel assemblies. First and second steering mechanisms can be coupled to the first and second wheel assemblies and the first and second support assemblies. A control system can be operatively coupled to the first and second steering mechanisms and can be configured to command selected angular positions of the first and second wheel assemblies relative to the base by compensating for the support assemblies being in various positions.
