Have been a Winlink user for years, from out at sea to at home. Just retired and plan on using it to stay in touch while camping out west. Just started with Vara HF and FM. Lots of fun getting it all setup.In my opinion its a fun and great way to stay in touch while out of cell service range. Another option is APRS via HF, and does not require connecting to a Winlink RMS. I have had good success getting relayed on hf into the aprs system and APRS-FI on Google maps, plus you can add a short text message IE: all is well. For hiking or biking away from my rv and hf rig I will be using a Garmin inreach while out of cell range. Have fun.
