Is ATRAC really better than old-school 4WD with lockers in your experience? I have my doubts but haven't seen enough to know either way.Not your question but if this is a dedicated icy/snowy road vehicle, look for a full-time 4wd with traction control(4runner or 100 series). If your heart is set on an 80, get an HF2AV and service the viscous coupler. But it won't be as capable as a-trac when it comes to sliding around on paved surfaces.
