As a local reseller/assembler (IMC), you try to woo as many buyers as you can, be it an urban user with no off-road requirement or a rural landlord/business owner with actual off-road and loader truck usage. At the end of the day, it's the sales that matter. No matter what the customer does with the truck. A leather interior, push-start, climate control does not mean Toyota positions Hilux as a comfortable family cruiser. It's just another option for buyers, nothing more. Look at how the vehicle is fundamentally built and where it shines and you'll get your answer.
Yes, even though D-max has better comfort with a similar suspension setup, it is still a far cry from a car. D-max too shines when you load it or take it off-road. It seems like your benchmark is wrong when reviewing the Hilux, your line of thought seems to be: given Hilux is an expensive vehicle, it is a luxury car, it should be ultra-plush and have all the creature comforts, hence everything becomes "Farigh". Price does not entail whether a vehicle is "luxury" or not, this should mean an 18-wheeler semi must be like a Rolls Royce.
Like others have stated above, a Prado would better suit your requirements. Also, if I were you, I would refrain from installing those jump seats in the back, they are highly dangerous, have no seatbelts, and are illegal as per law.
