Lower your tyre pressures and you'll be fine, a mate took his Kimberly Kamper over on one of our visits, and they weigh over 1.5 Tonne. He did get bogged on the Western inland bypass track when a vehicle came the other way, but I doubt he was running super low pressure at the time, likely 18 psi at best. Maxtrax got him out and going again. I towed a mates Cruiser through the middle of the island track when it had holed it's radiator, it weighs about 3 Tonne. Hardest part at times is getting off the Western beach, it can be pretty chewed up from people getting bogged not running low enough tyre pressures
