Stay away from any HOA's, people tend to make their own rules up. I bought in an HOA that specifically said I could park a RV on my property as long as it was shielded from view, the HOA just had the say on what kinds of shielding from listed examples. I have 1 1/2 acres. When I asked them what kinds of shielding, they said they were not going to approve any.
Big fight and in the end, I ended up taking over the HOA and stopped all the nonsense and making up of rules. The neighborhood has never been so quiet and no more fighting.
