The wind doesn't get rid of them, when it is raining, I think they go away, but they come back as soon as it stops.
Sounds like fun:), and probably a smart thing to do. I've been meaning to get my trailer moved to the arena so I can get Harley use to it. I'd like to tie him up all night to it here before I go to my competition. He did fine last year tied all night to a post. But he doesn't like being tied to a trailer.

Hopefully you'll have posts available... But if not, it'd be good for him to become accustomed. I'm nervous leaving them tied to trailers, there's too many edges and things for them to get snagged on. If he's the only horse with you, what about leaving him loose inside the trailer? Tiff and I did that with her big stock trailer, one in each compartment. Was comfortable for them, and safe.
Are you intending to practice tie him to it with the truck still attached? Or is it heavy enough you know he can't move it if he got into a pull back situation?
