How can I determine if my coach has this system?
You should be able to see some internal sensors for motion, glass breakage etc., housed high on walls small plastic enclosures. Also pop off breaker panel cover by step, a Trekmate "brain" in a labeled case will be apparent.
BTW, if you do happen to have a non functional Trekmate probably ought to go ahead and locate the wires that disable transmission engagement. As I recall they create an open in the neutral sensing circuit. Caused some head scratching in my wheelhouse....
