Can You Pass Through States with Stay at Home Orders?

When I'm in my motorhome, I'm in my home. I don't own or rent any other real estate. So I believe I'm obeying the law. I'm staying at home. I also went to Kroger and Walmart today, but that seems to be allowed. I'm staying in Texas for now because it hasn't jumped on the "close your state parks" bandwagon. The order I saw for Dallas County applied to residents of Dallas County. I'm not a resident of anywhere, except where I'm parked for the night.
