Re: easier state to register a trailer ?
NJ asks for receipts too, but all I've ever done is say I had the materials on my property and I bought the rest at flea markets and swap meets. They have a form where you swear to building it and certify its capacity and construction.
I've never really had a problem here. The problem in NJ is that they don't have a legitimate way to register a trailer by its manufacturer brand if the original registration is lost or if it was never registered. Forget it if you say you bought it from a non registration state.
The problem I run into is selling a trailer to someone from a neighboring state which has titles for small trailers. They won't accept a NJ registration as proof of ownership. I've gone through that with PA and DE.
NJ is worse with boats, I own a 12' boat that I bought new in Sears back in the mid 70's. Since NJ has never titled 12' boats, and at that time you didn't even have to register them, the only receipt I would have had is a register tape for a $230 purchase. When your 10 you don't worry much about saving register receipts. Now 35 or so years later they want proof of ownership to register it. They want to see a paper trail to the last registered owner, but there was none. I gave up and hung the boat back up in the barn.
I heard that NV is an easy state to get titles and registration through, a buddy in PA went that route to get papers for a tandem trailer that was under a boat he bought in NJ. The original owner had the trailer registered as homemade and PA won't accept that.
I think the service was International Title Service.
Maine will register trailers by mail you'll need either proof of ownership or a notarized bill of sale.
Age affects the cost, newer trailers need a title there and that adds to the fees.

The part that always gets me is how some states make such a big deal over registering a trailer that may only be worth a few hundred bucks at best, they act as if its stolen here if you don't have the the last registration and a notarized bill of sale from the last owner.
As if any thief would be actually trying to register it.
Maine made a business of trailer registrations and seems to do very well at it. I venture to guess that more than half of the commercial trailers I see along the east coast carry Maine trailer tags.
