Mine can hang over the door. Unless the aftermarket setup is different, but it is Mopar. Since the cap is plastic is there any real problem with it hanging against the body?@stuckinohio
Well, no way with the tether that is on there that you can hang over the door as you mention.
You could pretty easily alter / change the tether so you could do this.
Also, you could perhaps come up with a hook of sorts you could install in the cavity where the cap resides.
Another option... you could remove the tether altogether.. not recommending this but it is an alternative.
