Red Dead Redemption 2 has 5 Trappers. They are a type of Vendor that can craft special costumes and upgrades from your animal pelts and legendary pelts. After killing animals you can bring the skins to the trapper to craft them into something.
You can browse their locations by pressing (PS4) / (Xbox One) on the world map. This opens up an index of all markers and lets you browse between their locations by pressing / on the icon.
#1 – In Saint Denis, the main town in the bottom right side of the map. The trapper is on a market square.
#2 – West of Elysian Pool, south-west of Annesburg.
#3 – In West Elizabeth region, at the edge of the map to the east of where the river starts that flows into Owanjila Lake (west of Strawberry).
#4 – In West Elizabeth region, on a mountain north-east of Riggs Station.
#5 – In the New Austin area (accessible after finishing the story, until then you are wanted “dead or alive” and you will be shot on sight).
That’s all the trappers and their locations in RDR2.
