Well this has strayed from the original question but has opened another one.
The house is paid off so we are retiring and hitting the Open Road in our new R.V. traveling around the country and spending extended time visiting the kids that live in different States.
All our banking and bill paying is done over wireless internet and with the security system in our home we are not worried about it. Drivers License address remains the same. Coming back to the house is not so much of a need but rather a want.
So for the purpose of the BATF for buying a firearm how many days out of the year do I need to return and live in my house to qualify being a resident of that State?
ATF does not mention time limit.

" A person’s “State of residence” is defined by regulation in 27 CFR 478.11 as “the State in which an individual resides. An individual resides in a State if he or she is present in a - 2 - State with the intention of making a home in that State.” Ownership of a home or land within a given State is not sufficient, by itself, to establish a State of residence. However, ownership of a home or land within a particular State is not required to establish presence and intent to make a home in that State. Furthermore, temporary travel, such as short-term stays, vacations, or other transient acts in a State are not sufficient to establish a State of residence because the individual demonstrates no intention of making a home in that State."
Note the last sentence that says basically, when you travel somewhere else other than your home you can't claim to be a resident of that place if you have no intent of making it your home.
A couple paragraphs later it does a better job of explaining intention. Note the first 4 words "The same reasoning applies..."
"The same reasoning applies to citizens of the United States who reside temporarily outside of the country for extended periods of time, but who also maintain residency in a particular State. Where a citizen temporarily resides outside of the country, but also has the intention of making a home in a particular State, the citizen is a resident of the State during the time he or she actually resides in that State. In acquiring a firearm, the individual must - 3 - demonstrate to the transferor-licensee that he or she is a resident of the State by presenting valid identification documents".
"Held, for the purpose of acquiring firearms under the Gun Control Act of 1968, a United States citizen who temporarily resides in a foreign country, but who also demonstrates the intention of making a home in a particular State, is a resident of the State during the time period he or she actually resides in that State."
"Held further, the intention of making a home in a State must be demonstrated to a Federal firearms licensee by presenting valid identification documents. Such documents include, but are not limited to, driver’s licenses, voter registration, tax records, or vehicle registration."
