Don't worry about the boat, DMV don't have nothing to do with it, just register the trailer in CA, that's what goes down the road. I did it for over 20 yrs, not to worry!.
Sorry I missed you at Needles, I came over a couple of times but you guys were thrashing on the boat and didn't look too much like happy campers at the time, LOL, figured I better not butt in. See ya at Red Rock I hope!...
