Just a follow up one year from accident.
When I went to renew the trucks registration this year DMV told me they were informed by insurance the truck was salvaged so I had to get it inspected and a new salvage title issued. Side note because the truck has a gvwr over 10k lbs. most shops were limited to inspecting vehicles under 10k lbs. I ended up having to go to a big rig repair facility and DMV was really confused by the commercial certificate inspection certificate instead of the normal under 10k lbs certificate. Took me several trips to DMV to get it all in order.
As for the camper I was told truck campers fall under jurisdiction of Department of housing and not DMV in California. My camper insurance did renew so they do not consider it a salvage title apparently.
I hope no one ever has to go thru this but if you do maybe my experience will help
