Welcome to the Forum, we need more 3rd Gens owners representing.
To your thread question, I'm sure there is no argument that it is completely "possible", and maybe some can give example of how.
I don't think there are many (if any) states that still allow for that, and if they do, i'm sure (IMO) would require inspection and permit at minimum.
The research should be within your State, local laws. And/or whichever applicable states you may be traveling.
And the State/Local codes i'm sure would dictate what is acceptable/ unacceptable hook-up (if allowed).
Just my thoughts
