For early season work, I have a rack on the truck for drying the critters.
They blow in the wind as I drive down the road. This only works when the temp is above freezing. Mink and rats are usually dry when I get home, coon are usually almost dry. I take the animals that arent dry when I get home and hang them up by the front paw (coon, other large critters) and the mink by the head and rats by the rear leg. I take 550 cord and make loops and I have a meat board between my shed and a tree with dozens of screws in it. You would be surprised how fast the wind will dry them when they are hanging. Rain can be a problem though.
