I have no trouble with Roadtrains on dirt roads if they are coming towards me I just get right over to the left and pull up and wind up my windows and watch them go past, I have never had one pass me unless I was already pulled up, And I can not remember the last time I passed one, Caravans well that's a different story years ago I would get stuck behind one or two every trip, But not much theses days I think I slow them down as most have much more power than me, But once I hit the dirt to Weipa i have had a few close shaves, one bloke pulling a 18ft van was pulled up in the middle of the road on a blind corner taking photos of birds Lucky I have great brakes on my 4wd and trailer, another fellow coming towards us towing a 20ft van lost both his gas bottles off his Aframe and they came down the road towards us like missiles lucky they missed, We pulled up and helped him fix them up, Funny things you see on the road, Craig
