David's Pick
GL.iNet GL-X3000 Spitz AX
★★★★☆ 4.2/5 on Amazon
~$379
The best all-around router for RV full-timers — dual-SIM 5G lets you run T-Mobile and AT&T simultaneously and auto-failover between them without touching your phone. It needs a SIM from your carrier and some initial configuration; it is not plug-and-play out of the box.
