Starlink is fast but can drop under trees or in weather, so a router that fails over to cellular keeps calls alive. Only two products in the current pool are genuine RV failover routers, the Winegard Basestation 4G and 5G. Both accept Starlink over Ethernet and switch automatically.

What Matters Before You Choose an RV Router For Starlink Failover
Key buying criteria so you get the right fit the first time.
Ethernet WAN input
Starlink connects over Ethernet, so the router needs a WAN port to accept it. Both Basestations list Gigabit Ethernet. Check that the listing names it.
Automatic failover
Failover moves traffic to cellular when the primary source drops. Without it you must switch manually. Look for auto-switch wording.
Cellular modem class
A CAT20 5G modem supports faster speeds than 4G LTE. Faster only helps where 5G coverage exists. Compare the modem with your carrier bands.
SIM slots and carriers
Dual SIM slots let you keep two carrier plans ready, so a dead zone on one network does not end your backup. The Basestation 4G lists dual Mini SIM slots and names AT&T, T-Mobile, Verizon and Winegard FreedomGO plans. Check the carrier list and SIM size on the listing before you buy a data plan.
Operating temperature
RV interiors swing in temperature. The 4G listing states minus 22 to 158 degrees Fahrenheit. Look for a stated range.

Before You Bring One Home
How does Starlink failover work?

Do I need a cellular plan?
Yes. The router needs a SIM and data plan from a carrier or Winegard FreedomGO.
Is the Starlink kit a failover router?
No. It is the satellite source, not a failover router. Pair it with a Basestation.
Can I mount it outside?
The listings call it indoor. Keep it inside the RV.
