Thanks steveh27 for that pearl of information. I will tuck that away and hopefully will never have to turn to it.
All these ideas and thoughts are helpful. Thank you all. As I proceed, I must consider the whole house and community, as well as my other housing needs and desires. RV parking is only one aspect of the whole process. HOA's are pretty much out of the picture. Predicting what a community will decide in the future is useless except for an idea of general trends. Knowing what the "buyer's agent" is and is offering and representing is useful information.
With all the insight you all have presented, I can better keep my head up, eyes and ears open and make decisions that are right for me.
Thanks PapaRomeo
