Glad the inspector found the issues prior to your purchasing the rig. I'm not sure what "Life Safety" issues consist of, but 100 pages does seem to be excessive for a 4 year old rig. Posting outdated pics on an ad is certainly a serious red flag as well.
On the other hand, it is also not unreasonable for a private seller to sell "as is", although at a price that would reasonably reflect at least some of those needed repairs. After all, you are buying a used RV, not new.
I'm not sure I would ever be comfortable purchasing a big ticket item like an RV without seeing it myself, even with a professional inspection. Good luck on your search; hope you end up finding the perfect (for you) rig.
