In the end the only interpretation that matters is the city interpretation, or a judges interpretation if you take the city to court.
RV.NET poster's opinion will have no bearing on the city's interpretation, Im quite sure.
Asking folks here if you are "ok" won't mean a **** thing when it comes to arguing with YOUR city.
Im with those who ask why pick the fight now. If you like your interpretation, go with that, and if someone complains, then point out it's not motorized. Worse thing that would likely happen is you have to move it to a storage facility.
