If you can't move, the next best thing is: www.staabagency.com -- you'll receive a ME reg in your name at a ME P.O. Box.
I registered both my trailers for 7 years for under $330 WITH sales tax. & no title was required for my 9980 GVWR trailer. In MA, that would be my YEARLY rate, PLUS sales tax, PLUS title at $75!! This damn state got soo greedy with trailer registrations this past year that people are fleeing MA reg by the thousands. Can't blame them one bit. I'll never register a trailer in this state again ...... unless this state gets their collective heads out of their asses, and finally begins to realize that when you tax the ever-living *censored* out of people in a recession, you are just sending business over the border.
