With the high cost of gas now I am researching the possibility of installing a landscape bed on my 3/4 ton 2007 Silverado. I know it will fit and what the load capabilities are on my truck. What I am looking for is what the difference would be in gas mileage for my truck. We currently tow a 16' tandem axle trailer with 3 Standers and other mowing equipment. I average 9.5 mpg. Will I see much improvement in my MPG? Has anyone done this on a similar truck. It is a 6.0 gas with auto extended cab and long bed. Any input would be appreciated. I would be selling my trailer and the bed off the truck to help offset the cost of the installation. Also I was going to make it a dump-bed and have the dove-tail ramp removeable. Thanks for your input. Trent Roberts, Roberts Turf & Landscape.
