Thanks for the input Scotty, I will let yall know how the chains are when I have to use them. Don, I think the manual recommends using 18" wheels for the 4.8 because it has fender flare where the 4.4, and 3.0 doesn't? Thats why all other models recommends using 17" wheels?? I am not sure. Someone correct me if I am wrong. Thanks.
