Travel Trailers come in many different sizes and floorplans. Lengths range from 10 feet to 35 ft, with dry weights (without fluids or personal belongings) from 2000 to about 9,000 lbs. And prices from $10,000 to $100,000.
Travel trailers have their own heating, air-conditioning, electrical systems and water tanks. Smaller trailers have more compact space, usually with sofas or dinettes that make into beds. As you move up in size - full baths, kitchens, dining areas, and separate bedrooms are typical.
The use of slideouts and lighter materials in these trailer types has expanded living space without adding unwanted length or weight. Many travel trailers can be towed with a properly equipped full size car, SUV or pick-up truck. Many trailers will require load distributing hitches and other special devices designed to control sway, and make for a more comfortable ride.
