Hi Folks, Thank you for the replies, it has helped. The unfortunate part about all this from a 'to be' caravan owners point of view July next year, is, I live up here. I will have to take a better look for the Mudgeeraba sign refering to caravans, I have seen the one refering to trucks and tonnage. I agree with you about Pine Creek Rd, Nunimbah Valley, as steep as it is (12% - 17%) going up may not be a problem based on the power of the vehicle, and the weight being towed, it's coming down one particular part which is long and steep. I have been told not to use my High / Low range due to transmission strain and being on the Black Top. I have used my new vehicle across the Gulf, and up to Cape York (Tip) but that was easy going towing 1200kg max. Towing Ulti you didn't even know it was behing the truck. This is different, I have not towed this size or weight up or down the mountain. As to how the vehicle will respond I am unsure. I had brake fade once, with my Landrover Discovery towing Ulti off the Barrington Tops, in that instant I engaged high range selected third, and let it roll off the mountain with no problems. Thanks again everone for your assistance, I might put a phone call into Dave Gall, he may know the area, as he certainly knows caravans, from seeing his DVD's. Cheers
