I actually play solo because I can't figure out how to join a server(it always kicks me out :/) meaning I dont have a tribe and things to help me, so when I want to tame a carcha, I usually use a Rhyniognatha( you dont have to, any flyer works) because they are pretty fast and reliable, so I find a carcha(usually in the cold biome on The Island map), use keys to hatch a rex egg because its to cold to incubate, and drag it straight to the carcha without a trap because I dont have to worry about it attacking me, since baby rexes usually give 100% trust, meaning you can ride the carcha instead of it attacking you.
