What do you think of a ban on homeless RVs?

Those of you live in the Bay Area (and I know there are several here!) may be familiar with the housing crisis facing the area and the increasing number of people living in RVs. Many cities have a policy that RVs are illegally parked and must move within three days of receiving a warning or risk towing (this is the current policy in Mountain View, a city famous for being the headquarters of Google and currently considering an RV ban). This results in the RVs relocating before the three days are up but they are able to remain in the city indefinitely as long as they continue to move around regularly.

RVs are considered by many residents of these cities to be a blight on the community and they can be hazardous when they dump waste in storm drains or bring crime with them.

Some cities, like Mountain View, are considering a ban on RVs parked on many city streets, if not all.

Homeless advocates consider these bans criminalization of poverty and point out that no workable alternative has been provided (such as opening a vacant lot to be occupied by homeless people in RVs).

Does your city have an issue with homeless people living in RVs? Would you support a ban?
