The "Kansas Under 2M" tags that you see are not issued by the state, they are purchased at RV and Boat stores in the state if Kansas. Trailers under 2000lbs in Kansas are not required to be registered, that is true. These tags just fill the spot for the license plate.

I think you might have trouble explaining to a police officer why you have an exempt trailer in Kansas without a Kansas driver's license or a Kansas tag on your car.

Utility type trailers in my county don't require plates or registration and may not require lights if the towing vehicles lights are unobstructed. Just don't take it out of the county. Wisconsin is another state that doesn't (or at least didn't) require title, registration, or plates on trailers of a certain size. May not make them legal in other states. Temporary permits for crossing states can be notoriously expensive for 7-10 days of issue and they technically aren't good for adjoining states. The issue for the OP is ownership, domicile, and state registration. AZ requires state registration of aircraft and has an associated tax rate (which may be lower than Utah). I manage a few Colorado registered gliders and trailers that are visiting other states on long term arrangements. None have generated tax bills or state registrations, though I do receive the occasional toll road invoice. Colorado one time use tax was paid on each and annual trailer registration fees are paid on each trailer.
