RVA supplied the slide out hydraulics to the coach manufacturer who performed the installation of the supplied systems. So this means the specific finalized & installed wiring and plumbing information should have been documented by the coach manufacturer. Sometimes this information can be found in the coach manuals. The information provided here is the general guidelines RVA supplied to the coach manufacturers, and could differ from exactly how it is installed on a particular coach. However this is still helpful in finding out how the system operates.
