New Bulldog folding trailer and some DMV questions

So, I bought myself a Christmas present with my year-end bonus money , a Bulldog trailer: bulldogfoldingtrailers.com. I was originally set on the Yakima Rack and Roll, and though it's definitely not as pretty as the Yakima, the Bulldog folds up even smaller so it's more wife/girlfriend/small space friendly. They sell a few models, but I got the one for two kayaks. They're not cheap ($2k MSRP for mine), but I managed to score a sweet holiday discount code. I'll be putting it together soon and will update with some pictures.

Does anyone have some tips or advice on registering a trailer? Do I need to get a PTI (permanent trailer ID)? I believe my trailer qualifies as a utility trailer, but it's unclear whether they need a PTI. I have all the paperwork (cert. of origin, VIN number, mfg info, etc.) Also, I'm not sure if I need to bring the trailer to the DMV for inspection or if it can be done with just the paperwork. Thanks in advance for any insight, and have a happy new year!

PTi is a good thing, one and done. Yes I had to get mine inspected at DMV

Register, yes.
