Im actually using a Holden Frontera, this is a isuzu rodeo over in the US. I have the seats droped down and a cage on all 4 sides of the cargo area. I have been using this for the past 5 months without any problems. Have a roof rack for ladders, conduit etc. And if I have to do hauling of a lot of gear i just hire a covered box trailer to transport or pay a courier to deliver ( computer transport), never get a bill for there services as the bill my last employer for it.
As it is the only vechile I have when I need to use it for recreation the cage goes and the seats lifted up.
If i had the money I would go for this as my next vechile http://www.thesitecommander.com/ problem is Ford only bring in the F250 & 350 into Aus at about A$70K for the F250. bit pricey for my pocket
