I don't have the statistics at hand but I remember a study about road degradation based on vehicle type. The difference between industrial vehicles and passenger vehicles (including pickup trucks) was enormously skewed so that industrial vehicles were responsible for 80% of the degradation, Pareto-like. Meaning that heavier passenger vehicles might not make a difference.
