Hybrid travel trailers combine the features of a pop-up trailer and a hard-sided trailer. In their camping configuration, one or more bunks fold down from the side with canvas tent covers. When in travel, the bunks fold up into the side of the trailer leaving four hard sides. The primary advantage of a hybrid travel trailer is that it offers a greater space to weight ratio.
