I bought the Megalarm 3000 security system for my RV. The step-by-step instructions were easy and the wiring is color-coded. It has all the features I needed: 2 remotes, built-in 5 relays, multi-tone siren, ignition/starter cutoff, shock sensor, anticarjack sensor, negative triggers (door/hood switches), pager output, current sensing, flashing lights, status LED, passive arming, door lock/unlock relay, and battery backup. It is affordable compared to high-end alarms, and it is highly recommended.Get more detail about Megalarm - MEGA 3000 - 4 Channel Car Alarm Security System With 5 Relays On Board, Free Tilt Sensor.
