All fun ideas… just remember that (unless you’re also about to buy a satellite internet package) all of these devices depend on being online constantly and most of us don’t realize how valuable that built in cable/nether net connection is/was in our apartment.
Staying connected in a van is difficult and even moreso if you travel remotely and sled much time outside of urban environments (which I hike you will), so adding a bunch of WiFi enabled devices that suddenly can’t connect to the internet or to each other can become a hassle.
The more you can connect via Bluetooth and keep the system working regardless of WiFi hotspot or burning your cell data plan the happier you’ll be!
