In the state where I live, only four tractor marker lights are required to be mounted on the top front of my C70's cab. While replacing one of the lights, my friend told me that it's actually better if I install five lights, so my truck would be legal in other states as well. Is there any truth to that?
Yes, it would be okay to equip the top of your Chevy C70's semi cab with at least five lights as long as they are all amber lights. Installing five tractor market lights is actually more advantageous as they make your truck legal in all 50 states. Again, take note that these lights should all be amber lights as their purpose is to show the height of the truck's cab to the oncoming traffic, so they should not produce glare that could affect the vision of other drivers and pedestrians. When you already have these lights installed, make sure also that they are all functioning well especially when you're driving at night, or else, you're going to be pulled over and ticketed for having a busted tractor marker light.
I've been driving a Chevrolet C70 for a couple of years now, and I'm aware of the fuel economy standards set by the U.S. government for heavy-duty vehicles since 2011. Can you share some tips on how I can achieve a significant mileage improvement in my big rig?
Well, in a report issued by the U.S. National Academy of Sciences (NAS), you should be ready to make significant changes in your truck's aerodynamics, rolling resistance, and mass reduction if you want to comply to the U.S. standards' of 20% improvement in fuel economy by 2018. It also pays to invest in state-of-art features like "intelligent vehicle" systems that greatly reduce the amount of fuel burned by the truck simply by promoting driving habits that have long been known to help save fuel. For example: avoiding over speeding is one of the behavioral changes that you should practice if you want fuel cost savings, so it is wise if you can spare some money on electronic engine controls that could help limit your driving speed. Another benefit of operating at lower speeds is the reduction of aerodynamic drag, which translates to decrease in fuel consumption. You can also consider other on-board technology tools that could boost your C70's fuel economy by helping you keep an eye on and have control over what's going on behind your truck's wheel. If you aren't familiar with such technologies, you can always seek a pro's help.
I am aware that for drivers of tractor trailers like me, it is of utmost importance that the brakes are fully functional because brake failure on big rigs usually results in fatal accidents. So besides regularly checking on and replacing brake parts, can you give me other tips on how to properly maintain the brakes of my Chevy C70?
Your brake maintenance regimens should also include greasing the slack adjusters as they are the ones that keep your truck's brakes in proper alignment while they are at work. Your truck can have manual or automatic slack adjusters—both require grease to function smoothly. You should also inspect and grease the S cams—the components that shove the brake shoe into the drum to bring your truck into a halt. And, every time you replace your brake shoes, consider changing the bushings as well.
