It's all about pulling. The big one is rated to pull a boat, a big boat, and the little one isn't. The big one implies you have other toys, like jet skis or a boat or an RV.
Little guy.... your just hauling what you can fit in back.
Sure, the big trucks can tow. But that falls apart when you look at any various study about truck owners. Only a small fraction use the bed, towing, etc.
You can tow with a car or a station wagon just fine. Actually that's what families used for towing when the actual trucks were used in farms before the stupid CAFE standard in the US kicked in.
Wdym? There are Toyota(Corolla), Honda (Accord), BMW, Merc, Volvo, Audi, Subaru, MG and even Porsche station wagons in 2024. Where do you live? They are definitely available in the global and European markets.
Also you don't need a station wagon for towing either. A car with a decent engine and breaks will achieve the same.
