those that say the space is the same are kidding themselves
when you buy if you get a cab chassis (instead of a tub) build ute you can go to an 1800 long dropside tray (3m are good).
then stick one of these or similar on it (can make it higher and wider if you want)
trailerpartsdirect.com.au/shop/aluminium-canopy/aus-made-dual-cab-aluminium-ute-canopy/Plus i have an 80 litre water tank underneath with tap. dual bats. solar panel fridge. Can stick a 12 foot tinny on top.
I can fit oztents in the back if i want them secure and not on the roof (allthough I lock them on the roof)
I take fridges, eskies chairs, fishing gear, outboard, fuel, generator etc. try doing that with a wagon.
At the end of it all blow it out with a blower.
the absense of the wheel wells and the large area as well as the roof is way more than any wagon even with the seats folded. Its lower to load and unload and also a better shape. Add to that the tow capacity. Prado's are significantly down on the utes. My dmax is 3 ton GVM and 6 ton GCM.
Patrol's blow up. So if you want to tow approaching max then you need a full size cruiser.
4 cylinder rego much cheaper, tyres are cheaper. economy is good (similar to my wifes mazda sedan)
I see a dual cab as the only choice. Wagons are nice to drive but way too small and impracticle for me.
downside is rear seat sating. My wife is nearly a midget so she sits in the back sometimes as my son is getting quite tall. But I have sat in the back (6'2) for up to 500 k's with two other big blokes and its ok. I dont do that many long trips and short distances are ok.
Have a mate who had a mazda and he had no end of trouble and needed a motor replacement. Have heard lots of stories about them. Triton or DMAX although smaller have far less issues. Colorado might be ok. Hilux unnecessarily expensive and no better. VW meant to be nice to drive, but id be wary of them. I guess there's cruiser dual cabs but megabucks and then rego, tyres, economy etc expensive
the spings in all of them are soft for the showroom and loose their tension quickly. Cheapest fix is a leaf added in the rear by pedders. Front torsion bars are ok.
