Colorado's Redtail Overland differentiates RTC from RTT by sandwiching three hard sides between a carbon fiber floor and roof and packing in RV-style amenities like solar-fed lithium power and diesel heating. You'll have to bring your own kitchen and toilet, but the four-season Redtail roof camper takes care of warming shelter and power needs in a package that's lighter, more compact and more universal than other vehicle camper alternatives. We thought the idea of a hard-sided pickup camper was cool, and a hard-sided roof-top tent is potentially even cooler, providing a robust, weatherproof platform that can ride on a variety of vehicles, not just pickups.
