I have a pop up tent trailer that is longer than 16 feet. Currently it is registered and titled as a trailer coach and I have to pay yearly registration fees of $132. Is there some mistake with dmv, I see a lot of people with longer popup that are registered with PTI tags and that's significantly cheaper fees. Section 242 states that any tent trailer is a camp trailer and camp trailer is Not a trailer coach. Anyone fight this with california dmv?
