This is discussed on a lot of Class B forums and in particular Roadtrek forums. HOAs are thinking Class A and C and Travel Trailers when they make these rules but a Class B is still an RV - whether it is a second car or not or if one "needs" it for some disability - yes,that is often suggested - "have to have a bathroom wherever I go...". You could park it in your new driveway and no one may ever realize that it is anything more than a van - and then one day a guy with a Class C or A comes along and wants to buy into the community. He goes to the HOA and says "how can you say I can't have my RV when that guy has his RV in the driveway?". The HOA says "what RV" and he takes them to yours - shows them the vents, antenna, A/C, etc on the outside and you get a knock on your door - "get it out of here - its against the rules". Even if you get away with this for awhile this possibility is always hanging over your head - and even if the HOA says yes now, and that guy with the Class A shows up and protests, you will be asked to remove the B.
These HOA rules are not fair but they also are not secret and given to you before you buy. And if you buy in you agree to being aware of the rules and that you will follow them.
