We were away for a total of 87 nights, spending 2 nights on the ferry, 2 nights free camping between Bourke and Melbourne, and the remaining 85 nights in caravan parks. The total cost for caravan parks was $3,371.90, and ranged from $25.00 at Croki near Taree to $48.60 per night at Ashley Gardens in Melbourne during the school holidays. The average cost in caravan parks was $40.60 per night. Total cost on the Spirit of Tasmania for the return trip was $1,496.00 for a twin porthole cabin and the Navara with caravan at 12 metres overall length. We received a refund of $12.00 in carbon tax surcharges for the passengers and the vehicle for the return journey.
We travelled a total of 7,480 km including 4,874 towing the caravan. We used 1,396 litres of diesel at a cost of $2,195. Average fuel consumption towing the caravan ranged from 18.02 litres per 100 km to 27.55 lp100k (a particularly bad day) and an average of 21.1 lp100k. Without the caravan we averaged 14.2 lp100k. Fuel prices ranged from $1.479 per litre in Melbourne to $1.699 per litre at Bourke which wasn't so bad given we paid $1.669 per litre at Deloraine in Tasmania. The average price paid for fuel for the whole trip was a quite reasonable $1.572 per litre.
On the way home we put the rig over the local weighbridge and found that we were a little over-weight at 5.920 tonnes against a GCM of 5,805 tonnes. The fully loaded and coupled up weight of the Navara was 3.360 tonnes against a revised GVM of 3.250 tonnes. The fully loaded weight of the 5th wheeler was 3.200 tonnes against an ATM of 3.100 tonnes. The pin weight of the caravan on the hitch has increased over time from 550 kg to 760 kg. The caravan is about 100 kg overweight with most of the extra transferred to the Navara via the 5th wheel hitch. Our new annexe (weighing more than 50 kg) and a few cartons of wine accumulated on the trip were the main culprits. Before our next trip we will need to shed a couple of hundred kilos to be safe (and legal for that matter). Di thinks that the driver could make a start.
