Kimberly and Gibb River Rd

"it is not advisable to use one on this road"

Why? and who told you that? go for it as long as you know what your doing. Seek advice if/as needed.
Can you be more specific with what you plan to rumble down there with.

Just finished towing a Kimberley Kamper the entire length... and a lot of the road hadn't been graded - once section up north were still a single lane (basically a bush track) with grass growing either side of the wheel tracks. Towing vehicle was a Pajero.

The roads into the Bungle Bungles and Cape Leveque were far worse than the Gibb. We found the challenge in this road isn't because the road is particularly difficult in itself - the challenge is consistently driving to conditions along a very long gravel road - slowing down for the corrugations, approaching floodways and dips with care, and dealing with dust from other vehicles. UHF is a must - handy being able to communicate with other drivers to request passing, or let them past if you're travelling at different speeds (dust being the main issue).

Speed was key - the first dip or two remind you that braking on gravel for surprises like potholes or washouts is *not* going to stop you in time! We stuck to 60-70km for much of the track, and some sections required 40-50kmh for some distance. Given that usually you're only driving short distances between features of the track.... no need to speed like the Fritz in Britz brigade who take it at 100kmh.

Only drama we had on the road was a blowout on the trailer, from running too low pressures (followed someone's recommendations that were WAY too low!). Corrugations, overheating and a hard bump broke the bead, and even though I reckon I pulled up within a hundred metres, the sidewall was rooted. (Goodyear Silent Armour - 7000km old).

You won't need the snorkel on the Gibb itself - only place we required it was on the Mitchell Plateau Track crossing the King Edward River (100km north of Drysdale) - the river was at 90cm when we crossed. The Durack and Pentecost (as of 14th May - a month ago) were both <50cm. We didn't tow along the Mitchell Plateau track - we left the trailer at Drysdale.

imjames,
Go for it, dont let others scare you off, your car and camper will be more than adequate. Just drive to your ability. That road is busier than the M1 at the moment so you are not alone.

Drove it last Dec towing 14ft no worries lot of fun just watch out for the britz and other hire vehicles they pay by the hour and drive accordingly
