Serious Tow Vehicle

I decided that we might as well give the Van a go and get a proper tow vehicle.

What were my options?
-  Sounded like really need a 4WD. Whilst around Australia can be done with a 2WD, discussions showed that there were a number of places where you might be challenged if you only have 2WD and it would be really annoying if we couldn't go there.
-  This seem to limit us to a Toyota Landcruiser or Prado.  Vicki was not keen on a Troop Carrier (not sure why)  OK, maybe the ride it a bit hard, and you face it each other in the back for hours on end BUT hey, you get 11 seats and a hard ride should toughen up the kids right? I lost that argument.

Quick research into Landcruiser - they are expensive!  Do people really pay that much for a new vehicle?
I went to Pickles Auctions (www.pickles.com.au) and bid on a few that came through.  But I was not impressed.  e.g. 2006  Landcruiser, Diesal Turbo, 220000kms, 70000 km missing in service records, missing third row of seats, beaten about, rust on roof , chip on windscreen and sells for $36k plus transfer and on road costs.

Finally found a 1994 Series 80 Landcruiser, genuine 128000km, 4.5l petrol.  Looked like it had been owned by a old couple who had toured around Australia and then for the last 8 years or so had hardly used it.  Had twin batteries with a controller, bull bar, manual gearbox and drives like a new car.  A real answer to prayer.  Maybe $12k would be considered high but I am now seriously considering putting in LPG and keeping it after the trip rather than the Tarago as the running costs look similar with the LPG.
