1 Your liver makes and stores fuel. 2  Your liver makes glucose from carbohydrates (say car-bow-hi-drates) that you eat, such as ones in bread, fruit and dairy products. 3  Some of this glucose travels in the blood to the rest of the body where it is used for energy. For example the liver makes urea (say you-rear) from parts of proteins that can't be used. 2  It is poisonous so the body has to remove it. 3  Blood collects this urea from the liver and sends it to the kidneys. 4  They filter urea from the blood and it is then expelled from the body as waste in your urine.
Using any of these trailers Flatbed, Step-deck or RGN, the actual height of the load including the trailer height can not exceed 13' 6, the width can not exceed 8' 6 and the total gross weight including tractor (truck), trailer and cargo can not exceed 80,000 lbs. to be considered a legal load.
The GVWR is the combined weight of your truck plus your load. For example, my C30 weighs in at about 5,800 lbs. (I think) My license plates are only good for up to 8,000 lbs. GVWR, so the max load I can carry legally is 2,200 lbs. in the bed of the truck before I risk a MAJOR fine for being over weight.
