This is another one of my trucks I maintain in Iraq. The HET is an 8 wheel drive machine powered by a 12.1L Detroit Diesel V8 and a 5-speed Automatic transmission. The HET also has (2) 60,000lbs winches to help load any vehicle you are recovering or towing. The M1000 trailer is designed to to tow up to 70 tons and is very flexible with 10 bogies to equal 40 tires! The last 5 bogies on the trailer turn with the Tractor for better maneuvering. This trailer has a CPU generator for the hydraulic system to raise, lower, and tilt the bed. It is a very interesting design and a magnificent piece of equipment....Enjoy!
