When we talk about campers, we always refer to a specific classification: pure camper, upper cabin, semi-integrated, caravan. These categories are not just aesthetic representations, but have characteristics that make them suitable or more suitable for certain types of crew, special needs, number of people, camper's most frequent use. Then there are the tastes and fashions, but I have little to say about them.
A pure caravan (van) is a van (the manufacturer's original bodywork) set up to live in it. Ideal for smart couples, perfect for teenagers. Somewhat constrained interiors, but recently really innovative proposals have emerged, agility in transfers and parking (especially in vehicles up to 5.40 meters long). In fact, sometimes it is a 4-person caravan, but for me it is a 2-person caravan type. There's usually a rear double bed that's always ready, sometimes a roof folds up to accommodate two more seats (it can also be installed after market), in some cases the dining room can be converted to a slightly smaller bed, but I think it's for emergencies given the spaces and livability solution. It's important to experience the camper "outside" as well.
An upper cabin undoubtedly has the living unit placed on the floor of a van (therefore only the driver's cabin in the original superstructure), while an upper cabin rests on the roof of the driver's cabin. Spacious, it usually has 4 beds ready at all times while keeping the rest of the vehicle ready. The layout includes a double bed in the loft and a second double bed or bunk bed at the rear. Although there are many, it is the most common arrangement among families. A type of caravan for 4 or more people (evaluate the layout, consider seats approved for travel and weight ).
A semi- integrated is a no-top cabin (pardon the word for word), the same build typology is a 2-4 seater caravan, larger than a minivan, usually with a double bed in the rear and may have a second berth. but it is important that the lowered bed frees the entrance door, the dining room below is hardly used.
The camper is a vehicle designed from scratch in the open body of the van without the original driver's cab. Spacious and integrated spaces, double bed always ready and unfolds in cabin. Although it is a caravan for 2-4 people , it is preferred by couples. The large and comfortable dining room is a real living room. Sometimes it is considered (wrongly or correctly) by someone as a destination. Aside from the status symbol, which does not interest me much, it is a very comfortable vehicle for in-car life in general. The continuity of space and layout it offers eliminates the difference between cockpit and cell.
