The comparison is kinda unfair. The big truck has a wider bed, bigger tires and more power. It also seats more people. So it is able to get more load through more difficult terrain. However we can be quite sure it won't be used in that way.
up to but not including 7th gen hilux is more in line with what I would consider a reasonable truck design. I'd give them a pass before 2004 or so. The bulbous round ones, if people actually use them off the streets then it probably won't offend me to see them on the road but personally I'd just have a small car for day to day and only use the truck for what I bought it for, storage insurance when I don't need it. I'm still too scared of having my bike stolen to commit to no car it turns out. Some places are just too sketchy.
The tonneau cover is usually there because A) they do mostly highway mikes and want the improved mileage resulting from reduced drag, and B) they rarely use the bed, as those covers are a PITA unless you only remove it once in a great while.
I live in Central America where its mostly little trucks owned by workers, and they often drive on mud roads and hard terrain. The only people with trucks like the black one in the picture are US expats with ...particular political leanings.
unless the owner does a full handwash, clay, compound, and wax every time, there is no way the trucks I'm seeing in my region are washed off road vehicles.
In a way I almost prefer that to the blatant posers I see driving around with huge lifts and offroad tires looking spotless in our muddy season out here. I was at the combo laundromat/carwash the other day watching one of them wash an already clean truck while I was thinking about the massive mud puddle I'd be driving through to get home.
