I am looking at a 6500 4WD. I do a lot of loader work in the feed lot and cleaning up around the place (155+ acres). I currently have an older 5005 2wd and it has been adequate (sometimes just barely!). Is there a LOT of difference in the turning radius between 2WD & 4WD? I get in some tight places from time to time and might be too lazy to make a 50 point turn. Thanks, guys.
