Seriously, the Toyota Hilux (Diesel version of the Tacoma which was never sold in the US) was one of the toughest trucks of all time.
Why is there not a small/midsized diesel truck available in the US? The diesel engines are stronger, more efficient, and are capable of producing a TON of torque... it makes no sense to me as to why there isn't this option.
GM should look to fill this market segment. Make a nice, midsized truck with a decent sized diesel engine, and call it a day. And because it was my idea, I expect it to be called 'the Zeus'.
