Question on 450's/4500's

I have a 4-WD F-450 sitting in my driveway.

Agree that is all where one looks; up here in Los Anchorage, I don't believe I've ever seen a 450/4500/550/5500 without 4WD.

I just checked on Ebay for F-450 4WD and got several hits.
So, there are at least a few available.

I see many F450 and 4500 4wd trucks.
You mustn’t be looking in the right place.
