Yes you can use Starlink in an RV now. By enabling roaming mode on your Starlink account you are able to use your Starlink dish outside of your home service region. Starlink satellite internet is not able to be used while in motion at this time. Starlink is a great option for RVs that does not rely on cellular data and offers truly unlimited data. Pricing for Starlink is not cheap, but it is worth it for a solid reliable internet connection that is truly mobile.
