Claim:
A method for stabilizing an at-park travel trailer, the trailer having a frame and supporting axle or tandem pair of axles with tires, which comprises a) providing a trailer stabilizer system, said system having a pair of compound struts, each compound strut of said pair comprising: i) a base member having a footpad; ii) an extension arm extending from said base member, said extension arm having a foot end and a head end, wherein said foot end is hingedly mounted on said base member and a transverse pivot axis is disposed proximate to said head end; iii) an overlever arm pivotably mounted on said transverse pivot axis, said transverse pivot axis defining a fulcrum that divides the overlever arm into a long arm segment comprising a first end and a short arm segment comprising a second end of said overlever arm such that said long arm segment and said short arm segment have a ratio of lengths thereof, said ratio defining a lever with a mechanical advantage of 5 to 20 when pivoted on said fulcrum, said overlever arm having a cocked position in which said long arm segment is disposed on said fulcrum at an acute pivot angle above said extension arm and a locked position in which said long arm segment is disposed on said fulcrum at essentially a zero pivot angle relative to said extension arm; iv) a mounting bracket member enabled to rigidly attach to the frame proximate to the axle or tandem pair of axles; wherein said mounting bracket member is configured for engaging said second end of said overlever arm; and, b) cooperatively, for each compound strut of said pair, i) setting said footpad on a foundation; ii) engaging said second end of said overlever arm with said mounting bracket; iii) cocking said overlever arm; iv) manually rotating said overlever arm from said cocked position to said locked position, wherein one each of said pair of compound struts is installed contralaterally on the frame of the trailer at an axle or a tandem pair of axles.
