OK. The GVWR sticker says it all. Is it less than 14,001 GVWR? If it is, go get it smogged then go to the DMV and register it. The body type on the title may still be SB. They changed ownership on mine without changing the body type. As a result, I’ve been paying $20 a year in registration fees (don’t tell them)!
National General may offer you insurance while converting like they did for me
Convert, go to a VIN Verifier with the bus, change title to RV
