This Silverado is beginning to look more like a street machine than the dual-purpose vehicle it is, especially with the 9-inch-wide rims that are in this photo. Looks aside, the Leer shell was especially helpful on this two-wheel-drive by putting some much-needed weight on the lone drive axle. The change isn't as drastic as what the Detroit Truetrac differential offered, but it's enough of a difference that we now venture places that we didn't dare to try before. Or, it could be that we're relearning our 4x2 driving skills. Either way, we now have a comfy place to sleep when we get stuck.
