I live in an HOA that allows RV's in the side yard, the development was designed for just that- all the houses have RV gates. I can somewhat understand the thinking behind restricting RV parking. Aside from blocking views on streets (that can make exiting driveways a real treat) lots of RV's sit 50 weeks a year, with torn covers and other garbage piled around. On the other hand, lots are used regularly, are well maintained and look fine. As previously mentioned, its difficult to split hairs when writing ordinances- so everything gets banned.
End result, these ordinances aren't created in a vacuum, one must go to meetings and get active.
