The rear view mirror in the Travelall is about as useful as a tax audit. It’s a piece of flat mirror bolted to the roof, aimed back down a steel tube at two windows 15 feet away; there’s basically nothing visible in the tiny amount of reflective space. This is why I sought out and installed west coast mirrors, which will do the heavy lifting of showing me what’s behind the truck.
That being said, I saw an ad for a digital dash cam/rearview mirror on Insta yesterday and bookmarked it for future use: a product called Wolfbox, which includes a forward-facing dash cam and hardwired widescreen rear view camera mounted on a touchscreen that fits over your existing mirror. The more expensive models include stuff like collision protection, parking assistance, and other stuff that would require linking to the car’s computer, but I clearly don’t need that. If I could simply get a rearview dash cam that gave me a better idea of what’s behind me, I’d be very happy.
