Mates of ours are in the same boat with being on the hunt for a vehicle that can seat 4 adults comfortably on long trips and tow a car trailer with AU falcon race car (for speedway)
With everything they need to take for a nights racing their looking at something around 3 ton (spares, tires, toolboxes, jacks, etc, etc)
The first vehicle they checked out was the v240 dual cab 4x4 cause a couple of other racers use them and have nothing bad to say about them, apart from the stock power to weight ratio. The only reason our mates dropped the GW is their maximum braked tow rating is 2.25 ton. But their still looking at it cause they can grab a second trailer for the commodore that can tow the extras.
