Rodeo 2.8 or Hilux 2.7

Hi, I'm a newbie to this forum and also to 4WD vehicles in general, please forgive any obviously dopey questions I may put forward for a week or two :-)

I'm looking at purchasing a 4WD as a means of accessing where we are about to build, near Bendigo Vic. We'll probably drag the odd bit of tree around on the block (50 acres) as well as cart around the usual building materials, concrete, sand and so on. There won't be any serious 4WD usage - not for now anyway. But I don't think a 2WD is really up to some of the work we will be doing with it. Guess its a little easier to make a 4WD into a 2WD, but not quite as easy to do the reverse. I would estimate we will only be doing around 40,000kms per year.

Have been looking at a '97 Holden Rodeo 2.8TD and an '00 Hilux 2.7 petrol. They both have full service hist, Rodeo 130,000kms the Hilux 110,000kms. Both in low $20k Both have ARB Bull bars, rear step hitches and canopies. Rodeo has 113 litre fuel tank. Hilux std. fuel tank 65 litre I think?

I realise they are very different vehicles and have very different characteristics, but they are about as much as I can afford and both offer everything I need. However I'm not sure which one is better if such a decision is possible, as there are pros and cons (to me) for either of them.

Does anyone have -
-Comparative info on fuel consumption for either vehicle for
-light load highway driving conditions
-as above but around town (Melb.)
-Any good or bad experiences with either type of vehicle?
-Any advice on why not to buy one or other etc?

Sorry for the lengthy email.
