Traveling fulltime ... Sounds great... but what about Health Ins. Are you not yet 65? And what state are you going to use as your domicile. Domicile is the state you are going to declare as your new home state for all your banking, insurance, voting, drivers lic, etc. It is the state you now live in but not really. You have to declare it your new domicile and that you plan on returning to it after you are done traveling.
This is a .pdf from Escapees on all this...
Domicile info about TX but good info for all other states All this takes time but we on the many forums are her to help.
