I wanted a fun nature themed trailer hitch cover and did not find any I liked but I did find the fantastic slide trailer hitch with a blank version which is basically asking for stuff to be added. So I added the cute bird image to the top of it. Now a little bird can perch on your trailer hitch.

You will need the original 2x2 Trailer Hitch Receiver which can be found through the remixed model link. this slides into that. 

I have also created a squirrel and D&D logo models that can be used, see my profile for those.
