Dog Driller, Yea, me too. I would love to have a little trailer like that.
I have noticed that coyotes are different personalities. Some seem to be more cautious than others. Some are scared at pulling a large bait whether staked or not. Others don't seem to mind as much. They much prefer to grab a big piece and run off with it. Many times they will warm up to the staked-down bait after being initially scared. Gray fox are generally scared too of a larger bait whether staked down or not.
Here's some video clips to illustrate. This coyote is nervous at the bait, which is normal for most, but also he doesn't like the Ravens.
Click each of the photos to see the video.



Here he manages to get the carcass free from the stake, and carries it off.

Here is a clip of a gray fox pulling at the bait, as well as some other visitors.
Bobcats don't seem to mind a carcass staked down.
