Flat-towing – where the towed vehicle has all four wheels on the ground – is common in North America where it’s quite normal to see a motorhome flat-towing a Chevy Suburban or Ford SUV. The idea is that the motorhome is the mother-ship and the SUV becomes the grocery-getter once you’ve settled in somewhere with a nice view. They take their fun seriously, those Americans.

The practice is much less common here, but I’ve seen a few Suzuki Sierras and Vitaras and other small four-wheel-drives being flat-towed, so clearly it’s possible. As you’ve identified, a two-wheel-drive vehicle with a conventional manual gearbox shouldn’t suffer any dramas from being flat-towed. That said, I’d be careful with a four-wheel-drive, particularly a permanent all-wheel-drive example - because these are more complex drivelines and sometimes don’t appreciate being back-loaded.  It’s also worth remembering that a vehicle with a conventional automatic is a no-no for flat-towing as, unless the engine is running, the pump that lubricates the transmission isn’t working and the gearbox will be destroyed.

Unless the dealer can show you precisely why a particular year-model HiLux shouldn’t be flat-towed, I’d be a bit suspicious (especially when other dealers say yes) but the fact that nobody wants to offer you a warranty on a HiLux that’s being flat-towed also suggests to me that you could run into problems if there’s ever a claim.

It would also be worth checking what your insurance company says about flat-towing and don’t forget that different States and Territories have different rules and regulations. In Queensland, for instance, the law says that unless the unladen mass of the towing vehicle is at least three-and-a-half times the laden mass of the vehicle being flat-towed, you need to somehow make the towed vehicle’s brakes part of the package. On that basis, unless you’re towing your 1500kg HiLux with a vehicle that weighs at least 5250kg unladen, you’ve got yourself a problem that could involve the law and the insurance industry if something goes wrong.

If it’s damaged you should be able to see it. But to be sure it needs to be put on a bedplate, so I would take it to a panel beater or a chassis aligner who should have the required equipment.
