Toyota Hiace Van or Landcruiser Troop carrier??

[motoride]

After 2 year's motorcycle world travel,
I'm very tired of getting a wind,rain and cold,
also making a tent over and over again.
Now,I'm in Sydney and planning to travel around Australia for 2 years.
My conditions:
As acommodation here is very expensive,I should sleep inside my car everyday.
Especially,I love camping in the national park.
I travel single and carry very small luggage,such as a few clothes,
cooking stuffs,foldable chair,single matress and bicycle.
So I need a car which has
1.big room space
2.good fuel economy
3.reliable engine
4.everywhere parts availability
5.good resell price

Off road ability and big horse power are not important to me.
As I will travel along the paved road only.
When I travel motorcycle,the more gravel road,the more problem I got.
I think Australia has a good road everywhere.
More important is that I really need a reliable car,as I have no mechanic knowledge,
no mechanical failure on the road.

With my limited burget,I have to choice between

1.Toyota Hiace 3 seat van
2001 year. 160,000 Km. 3.0 Diesel engine
Fuel consumption 9 Liter/100Km (website search result)
Price: 17,000 AUD

Pros: Huge room for sleeping. (Even carry small motorcycle inside)
Automatic.(I love it..!)
Cons: No off-road ability. I don't know how strong this car.


2.Landcruiser troop carrier:
1999 year. 120,000 km. 4.2 Diesel engine
Fuel consumption 12 Liter/100Km (website search result)
Price: 23,000 AUD

Pros: Legendary all rounder...
Cons: low fuel economy

Which car I have to choose???
I never have a car before,so its very hard decision for me.
Which used one is more reliable to you??
