Welcome! Several people who are currently doing their conversions have opted to pull out the inner panels and replace the insulation. Some have found that their existing insulation was perfect, others found nasty mold and rust. It sounds to me like a lot of work. I didn't do it on my bus, but then again, I'm not living in my bus, and I live in a warm/hot climate rather than cold, so I'm not so concerned about this issue. If I were going to live in my bus long term, honestly, I don't know what I would do about removing panels, but I would give that option a lot more weight in my decision making. As it is, I just added some insulation to my walls and floor, and insulating beads in the roof paint, but due to space constraints, I really didn't add much insulation. In short, my bus is not very well insulated, but it serves my needs well enough.
