Camping vehicle such as an automobile or a towed vehicle (150; 250) for use during leisure time, comprising: - at least one vehicle wall; - a fold-out tent construction (101; 201; 301) which comprises at least one tent wall and, when the tent construction is being set up, can be moved from a stored state which is provided at least by the at least one vehicle wall and in which the tent construction is folded up, into a set-up state in which the tent construction is folded out; and - a frame structure for keeping the folded-out tent construction in the set-up state; the at least one vehicle wall and the at least one tent wall adjoining one another or being adjoinable to one another in such a way that, when in the adjoined state, they form part of a partition wall construction which, when erected, defines at least one inner habitable space of the camping vehicle (150; 250; 350), at least part of the at least one vehicle wall and at least part of the at least one tent wall each directly delimiting the at least one habitable space, characterised in that - the partition wall construction is provided with at least one inflation connection (104;204) for inflation means (108, 109) and comprises closure means (105, 106) by means of which all openings (107, 117), such as window openings and/or door openings and/or ventilation openings, which form a component of the partition construction can be closed towards the at least one habitable space; - the partition wall construction (102, 155) is designed to be inflatable by means of the inflation means, when the closure means are closed, from the stored state into an inflated state which temporarily occurs when the tent construction is being set up and in which state the tent construction is folded out at least in part due to the inflation means producing an overpressure in the habitable space; - the camping vehicle (150; 250; 350) is designed in this case to move the frame structure at least in part automatically into its operating state during the inflation process by means of the inflation means (108, 109); and - the frame structure which is moved into its operating state, at least in part, during the inflation process is designed to maintain a set-up state, which is reached once the inflation state has finished, without the overpressure in the habitable space. - at least one vehicle wall; - a fold-out tent construction (101; 201; 301) which comprises at least one tent wall and, when the tent construction is being set up, can be moved from a stored state which is provided at least by the at least one vehicle wall and in which the tent construction is folded up, into a set-up state in which the tent construction is folded out; and - a frame structure for keeping the folded-out tent construction in the set-up state; the at least one vehicle wall and the at least one tent wall adjoining one another or being adjoinable to one another in such a way that, when in the adjoined state, they form part of a partition wall construction which, when erected, defines at least one inner habitable space of the camping vehicle (150; 250; 350), at least part of the at least one vehicle wall and at least part of the at least one tent wall each directly delimiting the at least one habitable space, characterised in that - the partition wall construction is provided with at least one inflation connection (104;204) for inflation means (108, 109) and comprises closure means (105, 106) by means of which all openings (107, 117), such as window openings and/or door openings and/or ventilation openings, which form a component of the partition construction can be closed towards the at least one habitable space; - the partition wall construction (102, 155) is designed to be inflatable by means of the inflation means, when the closure means are closed, from the stored state into an inflated state which temporarily occurs when the tent construction is being set up and in which state the tent construction is folded out at least in part due to the inflation means producing an overpressure in the habitable space; - the camping vehicle (150; 250; 350) is designed in this case to move the frame structure at least in part automatically into its operating state during the inflation process by means of the inflation means (108, 109); and - the frame structure which is moved into its operating state, at least in part, during the inflation process is designed to maintain a set-up state, which is reached once the inflation state has finished, without the overpressure in the habitable space.
