The three most important things in the light weight car hauling business are weight, weight, weigh, and weight… OK that’s 4 things, but you get the point! Unless you're driving a big truck and operating over 26,000 GVWR weight management is one of your most important operating functions.
Let’s put for a moment 3- 2010 Chevy Malibu’s on our trailer. Give or take a little, the curb weight of the 2010 Chevy Malibu is 3,450 pounds, times 3 units for a total pay load weight of 10,350 lbs. Our Dodge Ram 3500 1-ton truck and 3- car Kaufman wedge trailer, with full fuel and a driver has a dry weight of about 13,000 pounds. Together the truck, trailer, and pay load roll across the CAT scale at about 23,350 lbs. Add a 4th 2010 Chevy Malibu and the total weight goes to 26,800 lbs, and a DOT officer is your new best friend at the weight station.
The 26,000 GVWR weight limit makes the 4 car trailer a bad mistake because the operator will NEVER be able to load 4 cars and stay under 26,000 pounds, AND will be operating with a heavier trailer on 3-car loads.
From a practical prospective we see it on the road all the time, 4- car trailers hauling only 3 cars, and operating less efficiently because a 4-car trailer is a heavier trailer with a capacity that will never be legally used. So in the light weight car hauling business less is more because a 3-car trailer actually yields a higher net pay load than a 4-car trailer, and you don’t have make new friends at the weight station.
