You're on the move.
Where are your bills (credit card statement, etc) being sent?
Where do you expect to settle?
If you had/have any income, in what state would you file a tax return?
If I was in your situation, I would set up a PO box for my bills and if a TX DL would not accept a PO box as an address I would ask a friend to use his address. Then, when I find the place where I plan to put down some roots, I make the move officially. The notion of having to change your DL every time you park your motorhome in a new state is quaint, in a man-without-a-country sort of way... but... unnecessary.
This is just my opinion. I am not a lawyer or a tax expert. I did not even sleep at a Holiday Inn Express last night.
