My perfect vehicle came out in 2016 and I bought one. See, I hunt and camp, haul firewood, and occasionally need to tow a decent weight trailer. None of this is done super regularly so a full size truck is not needed. First truck was a 1996 S-10. When I bought it, I had to decide between power to pull a decent weight trailer and get worse gas mileage the rest of the time during daily driving or get decent mileage while daily driving and not have the power to pull a decent weight trailer. I chose the latter and got the 2.2L 4 cylinder engine instead of the 4.3 V6. See, I wanted car mileage with truck capability and that's a hard combo to find. Second truck was a 2005 Chevy Colorado. Basically the same choices although the gap narrowed between the 2 engine choices. I chose the 2.8L 4 cylinder engine over the 3.5L 5 cylinder engine. I just couldn't justify the gas mileage hit of the bigger engine for the few times per year I needed more power.
During the time I owned these trucks, I kept thinking that a small diesel engine in this size truck would satisfy both of my needs. Good mileage while daily driving and enough power to pull a decent weight trailer the few times a year I needed to do that. I even toyed with the idea of putting a small diesel in my 1996 S-10 when it got older. Maybe a 4 cylinder diesel out of a Volkswagen or something but it always seemed like a job that I didn't have time nor money for so I settled with what I had.
That brings us to 2016. The Chevrolet Colorado came out with a 2.8L 4 cylinder turbo diesel option. Finally! My holy grail was here! Tow rated at 7700 lbs and rated at 30 mpg on the highway. I scooped it right up. Daily driving with a mix of city and highway gets me about 26-27 mpg which beats my other 2 trucks in daily driving mileage. On the highway, it beats my other two trucks as well and gets a lot better than 30 mpg. One 600 mile trip when all the conditions were just right, I got 36.6 mpg for the entire trip. 34 mpg is the norm for highway mileage. And towing you ask? I have pulled my ~4000 lb travel trailer on 4 different 1500 mile trips (750 miles each way) and it pulls it very nicely. No downshifting to extreme on hills like most smaller gas motors and 15.5 mpg to boot. So basically, car like mileage for the majority of my driving and power to tow and haul when I need to use it like a truck. All in one vehicle. No having a car for a daily driver and a truck for hauling and towing with two vehicles to insure, license , and do maintenance on. No driving a vehicle that gets bad gas mileage just so you can have the power to pull something a handful of times per year. It, for my needs, is the perfect vehicle.
