X3000 6x4 Dump Truck, Desert Spec, 430HP, Built for 50 Degree Ambient A truck that runs cool in Shaanxi can boil over in Riyadh by ten in the morning. This X3000 6x4 is the hot climate build: twin electric fan cooling pack with a larger radiator core, a two-stage sand and dust air filter, heavy duty dust seals on the cab and a 24 volt air-conditioning compressor that still cools the cab at 50 degrees ambient. Mechanically it stays conventional on purpose. Weichai WP12 at 430
