Abstract: An elongated strut having first and second large and small diameter relatively telescoped opposite end portions. The free end of the large diameter end portion includes a mount for mounting a corresponding vehicle side with the strut downwardly and outwardly inclined from the vehicle side. The free end of the small diameter end portion includes a relatively extendable spring biased foot portion for engagement with the ground and a generally horizontal brace is provided including a first end for anchoring relative to the corresponding vehicle side and a second end including clamp structure removably clampingly engaged with the strut small diameter end portion immediately adjacent and abutting the corresponding strut large diameter end portion to limit telescoping of the small diameter strut end portion into the strut large diameter end portion.
