About the Oasis 21'6
The Oasis is a 21ft 6in tandem-axle van entered through a mid door. It suits a couple who want wardrobe and bathroom space more than a third sleeping spot.
Tare is 2,550kg and Highclere quotes ATM at 3.2 to 3.7 tonnes, a range that spans the three build tiers. Ball weight is 210kg. Ask your dealer which tier a quoted weight or price describes.
A 6ft 2in pillow top inner spring mattress covers the front island queen. Inside, a large rear ensuite and big robes with drawers sit behind an angled door-side kitchen. The rear ensuite fits a full-height fibreglass shower, cassette toilet and 3.5kg top-loading washer.
The entry tier runs a gas and electric mini grill with a pot drawer. Carnarvon and Grand Explorer XT step up to a full oven. Reverse cycle air conditioning covers all three tiers. Fridge capacity stays at 188 litres until Grand Explorer XT lifts it to 224 litres.
The entry Dynasty tier carries one 100Ah AGM battery and a 210W panel. Carnarvon doubles the battery bank to two 120Ah AGM cells with 420W of solar and BMPro monitoring. Grand Explorer XT moves to lithium: two 150Ah cells, 630W of solar and a Victron 3000W inverter.
Standard water capacity is two 95 litre fresh tanks. Carnarvon carries a separate 100 litre grey tank as well. The system heats water on gas or electric power.
The chassis is Australian Supagal steel, on a 6 inch main frame and A-frame. Suspension runs semi off-road on Dynasty and full off-road on Carnarvon. Grand Explorer XT fits its own truss chassis and air bag suspension on top. The base Dynasty tier wears ribbed aluminium sides and a fibre roof. Carnarvon and Grand Explorer XT upgrade to composite aluminium sides and a composite roof.
Highclere backs the whole Oasis with a 5 year warranty, at any tier. Highclere builds the Oasis in Epping, Victoria and sells it through one dealer per state. Your state dealer quotes the price, and Epping takes Northern Territory enquiries direct.

Delivery and freight
Highclere Caravans builds to order, so you collect from the factory or have it delivered to you. Interstate freight is a real cost, often a few thousand dollars, and it climbs with distance, so budget for it.
