Just found this forum and your question about a vehicle.
We have just purchased another vehicle our 4th one!!!!!!
In our experience Land Rover is the pits. There are very few dealers and service agents in the world (comparitively) and Land Rover themsleves are EXTREMELY unhelpfull.
Our criteria for this last car was thought out - for the first time. Yes we are slow learners.
The criteria in no particular order was:*
Get into bed inside the vehicle (important in some countries. It isn't pleasant to have some one climb up to look into a tent on top when you are in bed!*
Keep the bed made up. I hate sorting out a bed every day.*
Small enough to force us outside when the weather is good. Too many people stay in their luxury camper vans.*
Large enough to manage inside if the weather is bad. It always rains in Europe and in many places in the world, like South America, it can be very cold or windy.*
Must be able to wild camp safely and with everything we need. i.e. totally self sufficient.*
High road clearance and an exit entry angle greater than 15 degrees. 4x4 is good but not absolutely necessary.*
Strong undercarriage to take rough roads.*
Tyres at least 16 inches. It is very difficult to find rugged tyres in 15 inch. ie in South Africa it is impossible.*
Friendly dealers and specialist servicing available worldwide. But any service station can be used most of the time. *
Maintenance is possible by a do-it-your-selfer.*
Not a high roof. Pieter keeps on forgetting how high the car is and scraping the top.*
Can stand up inside.*
Fits into a standard 20ft container - hi cap is OK. Although these are rare the shipper will find one.
We have recently purchased a Toyota Landcruser that has been converted into a camper van. It has a pop-up roof so fits all the height requirements, the bed can be left made up, it is small but you can manage inside. We are in Holland and have managed quite well in the rain, cold and wind.
You can look up the website www.vrolijksontrek.com
for a brief look at the vehicle and our previous versions. Australia is the best place to buy this vehicle and you are right there. Any search of the web will give you lots of possibilities. Then again you may not have our size requirements. You will also have an issue selling your car in Australia.
The best idea is to list your requirements and go from there. If you don't mind driving a truck, that is more spacious. If you want a built in toilet and shower you will need a bigger vehicle than a Land Cruiser. You can always have a pop-up roof if you need to ship the vehicle.
Hope this helps
