Funny, on hunts where we were, they encouraged you to use the truck to lean on. But those were all depredation, not once in a lifetime trophy hunts.The hunt is a lot of fun but you will spend most of your time glassing from your truck. The only time you will really be out and about is when you glass one that you want to put a stalk on. Just bring food, snacks and a lot of liquids. Bring a friend too as it will be a more enjoyable hunt. There will be Game Wardens out and about so make sure that you are doing things right. They can watch you from a long ways off. Saw someone get in trouble using their truck as a rifle rest when they shot their Oryx.
