I searched a long time to find a 3500, power everything, tow package, not white and with a 4.8 engine. The engine is not as underpowered as you think. On my worst tanks, I still get better milage then the older 6.0 with the 4 speed trans on their best days. On my worst tanks with hills and strong winds, I can still get 16+ and I run fast, even in those conditions. I have never found a hill or mountain that it wouldn't climb at full speed. Yes, it downshifts more often, but it does the job. It had 285 hp, what does a Sprinter have? The 6.0 is 330 hp. Not that different unless your drag racing. I can go 450+ miles on a tank of fuel, most 6.0 are fueling at 300 - 325 miles. I have carried 3,000 lbs through the Rocky Mountains and for some unknown reason, with their 85 octane fuel, I can pull 18+ mpg in the mountains. All of my best milage tanks have been with the low octane fuel and in the mountains. ???? If I get a new CV I will purchase the 4.8 again. I'm not racing, I just need it to be dependable and get me there as efficiently as possible.
