Patent ID: 7357440

Claim:
A method for naturally controlling atmospheric temperature within a camper, the method comprising: providing a camper having an upper portion, a lower portion, and a plurality of walls defining an interior; positioning a window to be received by a wall of the camper, said window being adapted to pass solar radiation in order to warm said interior; positioning a ridge vent to be received proximate the camper upper portion, said ridge vent being selectively movable between an open position and a closed position; positioning at least one side vent to be received by the camper proximate the camper lower portion, each of said at least one side vent being selectively movable between an open position and a closed position; adapting a solar curtain to removably cover said window to prevent solar radiation from passing through said window, wherein said solar curtain comprises a substantially heat-insulative panel defining a substantially heat-reflective surface; cooling the camper including the steps of: configuring said solar curtain to cover said window; moving said ridge vent to an open position; and moving each of at least one side vent to an open position, whereby solar radiation is limited from passing through said window while warm air is allowed to vent outwardly from said ridge vent, the warm air being replaced by cooler air venting inwardly from said at least one side vent; and heating the camper, including the steps of: configuring said solar curtain to uncover said window; moving said ridge vent to a closed position; and moving each of at least one side vent to a closed position, whereby ventilation into and out of the interior is limited while solar radiation is allowed to pass through said window and heat the air within said interior.
