I drive a cruiser mainly because most weekends I am towing two bloody great big thoroughbreds, total weight with float close on 3 tonnes, I drove down from Kinglake to Yarra Glen with no trailer brakes and it performed OK (who forgot to put the bloody plug in?).
This run is extremely steep and has some tight turns and can be quite acharacter building experience.
I drive this setup because I know what it can and cannot do.
My question is, why do you need a 4WD? Can't a medium size 2WD perform the same task for what you want without the excessive fuel bill and additional maintainance costs?
