If you have a 2 axle camper trailer this is a great tire pressure monitoring system. Sensors are very easy to attach to any tire. The monitor display is easy to read. The display shows the exact pressure in each tire as well as the temperature of each tire. This information is important to avoid sudden explosions in your installation. The system is wireless. I haven't had any issues with the inability to transfer information between the buses and the monitor. My setup is 26 feet. Each sensor is powered by a small battery. The kit includes a battery and a spare battery for each sensor. Batteries are easy to install. The monitor is powered by solar energy and charges the built-in battery in the monitor. It also comes with a USB cable if you need to connect the monitor directly. The sensor amplifier is included and should be attached to the lower front of your rig. The booster must be powered by your rig's battery. It has alligator clips that allow you to attach/detach the battery. I decided to remove the alligator clips and instead connect the monitor directly to the battery using the male/female connectors as well as the built in fuse to protect the wiring. This is a requirement for your installation.
