Camping World put out a notice to all members about this (at least in California). This is going to impact a lot of folks who park their RV in the driveway! I think that is the intent of the change in law. It will also stop Camping World and Wally Mart from allowing overnight stays.
In my neighborhood we have a couple of 5ers that park their rigs such that they have the hitch blocking over 50% of the sidewalk. Gotta be careful on the evening walks. Mind you I'm in an area of 1/2 acre lots with plenty of side yard access. Sometimes folks are just inconsiderate.
