Hi Trucks use ch 40 , caravans seem to use ch 18 the most and a lot of 4WD groups in WA use ch 10 , not shore about up north for 4x4s groups

When in the bush it's a good idea to set your UHF to scan, if it can. That way you will hear anyone calling up. If you get in trouble, find the local repeater channel and call on that for help.
Have a good trip.

as already mentioned, channel 40 is the common highway channel, and many caravan organisations are pushing channel 18 for caravanners.

the recommended 4wd club channel is now 12, but it was 10 for many years and you'll still find it used as well.

Displaying a callsign/channel on the back of your rig is a good idea regardless - lets people know you are listening.

Go with Ch 40 - the Truckies know what's happening. Display it - better have a road train driver let you know he's approaching fast from behind, than scare you by roaring past out of nowhere. Just don't let the kids listen in to they chit chat! Some of the caravanners display a different Ch (generally 18) - so you can switch over to speak to them if need be. Over and out

If you have kids you can also spend $89 from dicksmith on 2 x handhelds (like uppy did) and the kids can use the little 2x handhelds when they are out playing in the bush (and you can listen in on your car uhf) and then you can set one of the handhelds to scan all channels while driving and leave you main UHF on 18, 40 or whatever you prefer.
Perfect example of how this works effectivley was when Uppy and I were in Dwellingup last weekend. We both had handhelds scanning. We were talking on our nominated channel and I heard some people loud and clear on channel 27. I slowed down and there they were around the corner on a very narrow track with trees on both side. We were then able to talk to them on their channel guiding them past while we were still talking on our channel. Works great.
Other option as mentioned on previous posts is to use group scan etc, this does work, but I don't feel it gives you the same flexibility, however others may disagree. For $89 with chargers and handsfree sets it's good value IMHO.

So where the big trip up north going to be ? The war office and i will be someware on the GGR end of may early june , take a look at the rig pic,s and keep an eye out for us and come say ga,day if you see us . Errol.

Terry I assume you have a caravan. I addition to channel posting on the back also post the channel on the top offside front of the van as vehicles going the other way can call you. I have seen a number of poptops come loose and there is no way to call the caravanner concerned. I Queensland use CH 40 as priority and scan the others if you wish.
