Even by Technic standards I was appalled by the turning circle of this truck, so I modded it with drastically improved steering angle, lowered the engine so it's not coming right up between the seats and gave it a tilting cab. Admittedly the tilting cab doesn't really look like any tilting cab I've ever seen, but at least you can see in underneath now :)
