This is the all new SABRE 28RBFWS travel trailer. The RB stands for rear bath, which is very large and features a large neo-angle shower. The FWS stands for full wall slide, nearly the entire off door side is one gigantic slide out. The sleeper sofa, the dinette and the full residential size queen bed are on slide. The 28RBFWS has a huge kitchen, bath, and bedroom, and boasts enormous amounts of storage, in, and out. The 28RBFWS has all the standard options plus, options you would not expect to see, on a smaller unit. The adjustable air bed sleeper sofa and ten gallon water heater are just a few of the endless list of options. The smooth fiberglass exterior gives the finishing touch to the Sabre’s 100% welded aluminum super structure. The luxury and quality will speak for itself, when you see the amazing 28RBFWS by Sabre.
