The GiraffeG4 Overhead Collision Alert System provides you with an accurate measurement of that overhead obstacle from inside your vehicle! The driver pulls the GiraffeG4 exterior sensor under the overhead hazard. For 5th wheel units, the magnet mounted sensor will be on the roof or hood of the tow vehicle. For Class “A” coaches, the single arm mirror mount will attach to the side view mirror.
