Just to get this back on topic. I did get my truck finally registered as non-commercial. This involved some long and frequent conversations with the bank to send the title over to DMV. The bank (Chase) kept insisting that they dont really have a physical copy of my title, that it is all digital, therefore they have nothing to share with the DMV. Finally, they did send the title over to the DMV and the rest was straightforward. DMV sent the bank the title back and I saved myself $150 atleast a year.
Now I have to remember to never take the camper off!
