Colorado Regulation 39-22-103(8)(A) specifically states:
Once a person’s domicile is established in a state, it will continue to be the person’s domicile until the person establishes domicile in another state.

Therefore you must file as a full-year CO resident until you establish a new permanent home - a new domicile - in another state. Living on the road or in temporary lodging such as hotels does not constitute establishing a new domicile.
