<P> Basic popups usually include the following features: fold - down dinette (table top and bench seating combination), on - board fresh water tank, sink, 12 - volt DC power system (including an AC to DC converter and a deep cycle battery), interior DC lighting, two sleeping bunks and storage cabinets . Many pop - ups also include a gas / electric absorption refrigerator, stove, rooftop air conditioner, propane furnace, water heater, electric water pump, exterior shower, skylight / roof vent, one or two propane tanks, electric or surge brakes, large storage trunk at the front of the box, and an awning . Some premium models also include a shower, toilet, wastewater tanks, slide - out section (to increase interior space), microwave, and an oven . </P> <P> Since space is at a premium in popup campers, it is common for a single structure to serve multiple purposes . Generally, the dinette, which can seat four people for a meal, can be converted into a bed to provide additional sleeping space . Likewise, the couch, if present, can usually be folded down into a bed . Often, the inside table (part of the dinette) and the gas stove can be taken outside and attached to the side of the camper . </P> <P> Modern pop - ups range in weight from approximately 700 pounds (320 kg) to 3,800 pounds (1,700 kg) pounds empty or full . Models are generally classified by the length of their box, which ranges from 8 feet (2.4 m) to 16 feet (4.9 m). When opened, the length is roughly double the box length . Most pop - ups are between 7 feet (2.1 m) and 7 feet 6 inches (2.29 m) in width and between 4 feet 6 inches (1.37 m) and 5 feet (1.5 m) in height when closed, but "high wall" models are tall . Published sleeping capacities range from 4 to 8 people . </P> <P> To open a pop - up, the trailer must be chocked, disconnected from the tow vehicle, and leveled . The roof must first be raised using a winch that extends telescoping poles on each corner of the box . Next, bunks at the front and the back of the trailer are pulled out by hand . Then, the tent material (which is fastened to the box and to the roof) is unfurled, pulled over the ends of the bunks, and attached . Interior support poles for the bunk and the entry door are then installed . </P>
