Tools and technology. Backing up a 25-foot Airstream by yourself can be a bit intimidating so I'll be relying on technology to help me out. The image below shows three monitors inside my truck cab. The first and largest monitor is for a wireless, digital Voyager backup camera; the read out says "No Signal" because I wasn't hooked up to my trailer when I took this photo. The Voyager camera is mounted on the back of the Airstream; and transmits a wireless signal to the monitor; it will help me backup into campsites but it is also great for monitoring cars behind me, including those about to pass. The second monitor (color monitor to the left; built into the dash) is for the backup camera that came with my pickup; this monitor helps me line up my hitch when I'm hooking up the trailer. The third monitor in this image (below the larger Voyager monitor) is for my Tire Pressure Monitoring System (TPMS) that monitors the temperature and pressure of the trailer tires as I drive. The TPMS continuously monitors temperature and pressure and emits audio alerts when either changes too fast; the alerts will (in theory) allow me to pull over to the side of the road before tire blowout. The Voyager and TPMS monitors are mounted on a swiveling JottoDesk. All this technology makes me feel like an airline pilot when I'm driving down the road:) but hopefully it will help keep me me (and those around me) safe and avoid expensive accidents. I had no idea this stuff existed until about a month ago:)
