Interesting. I started looking into it at one point (talking with the fire
marshall, etc) but eventually lost interest. A trailer would be ideal since I've got

There's a national code which will apply to Freeways and US highways.
Your state may or may not have different rules, they probably do.
Likewise your city may have rules.
