A system varies space of a vehicle having a first portion with occupiable space and a number of ground engaging wheels coupled to the first portion. A second occupiable portion is coupled to the first portion and configured to move relative thereto to adjust volume of an occupiable living space defined by both portions. A pair of support arms are coupled to the first portion which each have a bearing member engaging a guide of the second portion. Each bearing member is permitted to move relative to an axis perpendicular to an axis of travel of the second portion to relieve stress from forces acting on the system which are nonparallel to the axis of travel. The arms are positioned by an operator controlled positioning mechanism. In another system, an arrangement of telescoping arms is disclosed for positioning a first occupiable portion relative to a second occupiable portion. This arrangement includes an operator positioning mechanism with a rotatable member formed from a self-lubricating polymeric material. The rotatable member is configured to movably engage at least one arm and correspondingly position the first portion relative to the second portion to adjust volume of an occupiable living space defined by the first and second portions.

[ What is claimed is:] [1.] A system for varying space in a vehicle, said system comprising:an occupiable first section with a number of ground engaging wheels and a first wall connected to a first floor;an occupiable second section coupled to said first section and configured to move along a first axis from a first position to a second position relative to said first section to adjust volume of an occupiable living space defined by said first and second sections, said second section being occupiable in said first and second positions and having a second wall, a second floor connected to said second wall, and a guide;a pair of load bearing arms, a first end of each of the load bearing arms being fixedly coupled to said first section and configured to support said second section, each of said arms including a bearing member pivotably mounted thereto distal to the first end thereof, each of said bearing members engaging said guide to move said second section along said first axis, each of said bearing members being permitted to move along a second axis in response to a force component acting perpendicular to said first axis when said second section is moved, said second axis being generally perpendicular to said first axis; andan operator controlled positioning mechanism operatively coupled to said arms to selectively position said arms and correspondingly position said second section relative to said first section.
