Toyota built an 18 wheeler.
To be honest, I haven't seen a quality aerdynamic truck yet. My volvo is nice, but the interior quality is severely lacking, among a few other things. From talking to other drivers, they think the volvo is the best among aerodynamic trucks. Why cant petercar or kwhopper make a quality aero truck? I guess the t6 is a step in the right direction, but lack of storage space turns me totally off.
If Toyota stepped up to the plate, I think they could make a quality product in a very short time. It wouldn't have the long hood, or the chicken lights everywhere, but I bet it would be a quality truck.
