> I occasionally need the hauling capacity [of a] 1998 Ford Ranger

Then rent a suitable vehicle for the occasion.

- Your example Ford Ranger[1] seems to have towing capacity of 6,000lbs (~2700kg), and a payload capacity of 1,260lbs (~570kg).

- Compare that to the worst model Toyota Hilux[2], which has a payload of up to 1240kg, and can tow 2500kg. These can be rented for like $65 AUD per day (~$40 USD).
