I bought this to replace my 04 extended cab Z71, it's an 04.5 2500HD crew cab with a Duramax(LLY)/Allison combo with 70K on it. Our roads are a mess right now since we've been melting away so she's a little dirty. I bought it for more than just hauling wood but it will do a fine job doing that also. Can't say it was a need, I've wanted a big stupid diesel for a long time. The kids are growing and the extended cab just wasn't cutting it anymore.
