With a huge range of tow vehicles available, it is no wonder travel trailers make up the majority of towables on the road today. While these units are generally smaller than fifth wheels, they offer better fuel economy because of it. Less weight equals less work your tow vehicle has to do to pull your RV. Travel Trailers are generally easier on the wallet making them an easy choice for people. Some folks do not care for the multi-level floorplan that comes with a fifth wheel, so the single level floorplan of travel trailers makes them that much more appealing.
