Can I take my internet service on the go?

Now with the stay at home orders, I need to be working remotely.  How can I take my internet service with me?  I am needing to stay at another location for a few days and I have researched that there are no xFinitiy wifi hotspots anywhere near.  😞  Therefore, is there a router or some additional kind of service that I can purchase that will allow me to have internet service on the go?  I will be staying in my RV, so I have a home on wheels.
