Travel Trailer Liscence Plate

[Nufy]

Do you keep it or sell it with the Trailer ???

Keep it. It belongs to you forever.

If you ever have a trailer in the future you can just slap in on the new one.

And if you give it away with the trailer, you could be on the hook for red light camera tickets, etc/

Those things cost ~$135 these days. A buddy of mine has had three of them stolen in the past two years.
But yeah, as Ken said, keep it. It's yours forever. You can put it on whatever trailer you're towing. It's connected directly to your driver's license. If you get tickets on it, you won't be able to renew your registration until you pay them off. Doesn't matter what you're towing, you can pretty much put it on anything (within reason, pretty sure a 53' semi trailer needs a certain plate).
