This 2-story RV with a kitchen, bathroom, and bedroom can detach to be its own tiny home - see inside

The camper's sustainability theme can be found throughout the vehicle.

For example, there are solar panels on the tiny home, and its wooden walls — which are processed to allow it to stay rot-free for 25 years — come from "well-managed sources," according to Haaks.

Haaks also makes an effort to source its parts from local suppliers.

The Opperland's kitchen has several amenities found in non-camper van kitchens, such as a sink, an induction cooktop, cupboards, and a drawer.

The cooktop and 81-liter fridge and freezer are powered by a 360-amp-hour lithium-ion battery.

The camper also has a bathroom with a toilet and shower, a seating area, and interior and exterior storage spaces.

There is also an inverter, a water heater, and 45-liter fresh and wastewater tanks aboard the camper.

In line with the "freedom" theme, the Opperland was designed to allow people to have more of a connection with the outdoors, according to Haaks.

For example, the camper has large windows that bring in plenty of natural light and views of its surroundings.

A wall on the lower level can also pop up, creating an open living room that connects the indoors to the outdoors.

The upper level expands into a bedroom, allowing for a more spacious living area on the lower level.

The upstairs bedroom can be accessed via the camper's "goose-step" staircase.

The bedroom has a 5.9-foot by 6.6-foot bed topped with a foam mattress.

The camper's layout can be modified according to the customer's needs and visions.

The production of the campers is controlled by a computer …

… while the assembly of the camper is done through a process that emphasizes quality and precision, according to Haaks.

The camper portion can be removed from the Fiat Ducato to stand independently with its own expandable support legs.

This allows the camper to be used separately from the van.

The camper unit itself is about 13 feet long, 7.5 feet wide, and 8.3 feet tall.
