Hybrids can get to remote locations that caravans cannot. The build is fundamentally different to that of a caravan with a sturdier chassis and draw bar and an off road suspension ready to soak up the corrugations. A higher clearance is required to enter and exit washouts and a narrower body helps to squeeze down off road tracks. A shorter, lighter body and longer draw bar allow for a better turning circle, off road stability and nimbleness.
Likewise to withstand the corrugations, the internal cabinetry is made of screwed, glued or bolted aluminium and composite panels rather than stapled ply wood.
Well designed hybrids are easier to tow on the highway as well with none of the sway and wind resistance issues that plague some caravans.
Internally a hybrid is much like a caravan with a large bed and bunk beds for children, and depending on size, a toilet, shower and seating area. However, the cooking facilities and fridge are usually outside under an awning for that camping atmosphere, so cooking smells do not permeate the furnishings and cooking is part of outside family life.
Set up time is similar to a caravan with everything ready to go minutes from arrival.
The undercarriage is galvanised for beach work and the body is made of corrosion resistant materials such as aluminium and composite panels.
Modcon hybrids have a substantial off grid capability with water and power being the first things you run out of when remote camping. Water carrying capacity is at least 240 litres and battery capacity 200 amps with a BMS that allows both 12v and 240v charging from a variety of sources. Charging from the car, solar and generator are off grid staples with mains power charging available when you come in from the wild to restock at a caravan park.
Awnings are the roll out type or for more coverage and versatility a 270° swing around variety.
Additional luxuries can include water and space heating that does not rely on 240v power and air conditioning that can be run off a generator (although the latter is often banned in National Parks).
Caravans are mostly designed for van parks, with mains water and power being plugged in upon arrival. Hybrids are designed to be independent of all that with the ability to get remote and stay there.
