I drove in to the California DMV in Long Beach California from the

Total time...less than one hour.

Well, believe me or not I got my trailer registered before it went
through the customs and now I can not get it through customs because
they need a document that essentially says the same thing as the plate
on the trailer. Did you show a trailer's plate to customs or did you
show a document stating the trailer met federal regulations, bla bla
bla...
