We previously had a Hi-lo trailer before upgrading to a 25' travel trailer. The big advantage of the Hi-lo was better gas mileage (less frontal area) and easier towing. The disadvantage is the storage space. I really liked the Hi-lo but we came across a great deal on a full size trailer and aren't sorry for the change. We now have a closet for hanging clothes, a larger refrigerator and a slide-out couch for added room.
