Something along the lines of the old Rangers and S10's from the 80's and 90's is what I'm thinking. They sold like hotcakes, and weren't as feminine looking as a scaled down Honda Ridgline.
Shoot, those are as big as full sized trucks were 20 years ago. I'm talking a truly compact truck for someone that doesn't need a massive amount of towing or hauling ability, but still wants a truck.
