Asking for a friend - Because I have similar ideas - AP/router hardware recommendations for RV

I'm looking for hardware recommendations for the depicted setup, with an AP/router running OpenWRT in an RV. Requirements:

• Compact footprint: Very small equipment cabinet in RV.
• Stable (unattended connectivity with light traffic for months).
• Dual radios to support simultaneous WIFI uplink to Internet gw, as well as acting as a WIFI AP to clients.
• 802.11ac or better WIFI speeds.
• 1 Gbps or better Ethernet ports (at least two).
• Light traffic over Wireguard link to home base (telemetry).
• Low power usage preferred, 5V or 12V power supply preferred (available without shore power).

Any ideas? Thanks!

My thought was to also add a Starlink Connection using ethernet adapter for when no wifi or Mobile signal is a available and montior the bus with HomeAssistant for security and power management.
