For most older domestic truck engines, there is the “RV Cam” which maximizes low end torque, and fuel economy. There may be a similar option for your truck. Of course you’d lose top end power as well. You’re driving a 20 year old 4 banger pickup truck. It was about the most fuel efficent small truck when it was new. It’ll be hard to improve on it.
