Air OPUS camping trailer inflates into a home away from home in 90 seconds. When we first discovered the British-designed OPUS camping trailer back in 2013, its combination of compact pop-up construction and comfy interior design made it one of our favourite campers of the year. Since then, the OPUS has gotten a few extra tricks up its sleeve including an all-new tent inflation system. With its integrated air poles, the new inflatable AIR OPUS trailer tent sets up in about a third the time of the original.
