Hey guys, new to the Skoolie hunt for a decent bus. My wife and are excited and she is already drawing floor plans on graph paper. My question is regarding a bus that has already began a conversion. It's a 2002 Bluebird with a 3162 caterpillar engine and Allison transmission. All seats are out, new ceiling ac, new generator mounted underneath bus. The seller just doesn't have time to complete the project. Everything looks good, sounds good, engine ran well and test drive went well. My concern is when I looks under the bus it appeared to have quite a bit of rust which the seller said was just surface rust. I am attaching some pics of the rust to get any thoughts you may have. We are very interested in the bus until I saw this concern.
