It's all relative. 150lbs in a 3500lb truck is around 4% of it's weight, and for a pickup truck, the ratio of energy needed to roll the vehicle compared to the energy needed to push the vehicle through the air is about 1:1-1:5 depending on whether you're driving along at 25mph in the city or doing 70mph on the freeway, so you're looking at a .8-2% difference.
