There’s more to consider than just “I am comfortable”, imo. Fuel economy, wear and tear on the roads, and safety (for you and those around you) are important factors as well.

Bigger and heavier vehicles tend to have worse fuel economy. This not only costs the owner more money, but it also is worse for the environment. However, this may be an outgoing trend as more hybrid/electric pick up trucks and such are coming to market.

Bigger and heavier vehicles cause more wear and tear on roadways. This, in turn, increases the frequency of required road maintenance (read: requires more tax revenue), or else the road may become treacherous to drive on.

Bigger and heavier vehicles are proven to be safer (aside from rolling) for passengers in many regards - the size makes it safer for passengers inside the vehicle, since there is more car to take the impact before reaching the passengers. In a vehicle collision, the passengers in a heavier vehicle are safer than the lighter one, as the heavy vehicle will put more force on the lighter one. This is good for the passengers of the heavier vehicle, but much worse for the others.
