If there is no HOA, the CCR's are not a problem. Local law enforcement in most states will not enforce CCR's. A CCR is not a law!
We have a short page of CCR's, but no HOA. RV parking is not forbidden.
Not far away, there is a new development that has very restrictive CCR's, and the developer has created an HOA. However, I see RVs parked beside house there, so perhaps it isn't too bad. I have to wonder, though, what prompted the developer to put in the CCR's that no aircraft are allowed on the properties??
Here are the preliminary CCR's:

Perhaps the buyers forced changes on the developer. The referenced website is the current list.
Needless to say, I would not buy land there.
