a removable drawbar w/ hitch ball under your rear bumper?
That.
I think someone is BSing you.
Some "hitches" are offset with a rise that might make the tag not completely visible, which would seem to violate 13-411(c)(2)(iii) of the Transportation code.
Like mine?
Possibly, but your saving grace would be those letters at the bottom of the tag.
Can't read anyones tags when they are pulling a trailer anyway.
Trailers don't have tags?
Yes, but different than the tow vehicle.
