The manual doesn't mention any jacks or stabilizers. http://www.winnebagoind.com/resource...013/13View.pdf
Stabilizers are just 'props' under each corner to reduce bounce from suspension and tires when moving about inside. You could use scissor or hydraulic jacks or buy the type that fasten to the RV frame and fold up.
Jacks use a reservoir, pumps, and hydraulic cylinders that usually have to be professionally installed. Consult Winnebago and see if they have recommended systems and anchor locations to prevent frame damage.
