I really want to just go put something under the wheels but I’ve never talked to these people.
Update edit: thank you for all the replies. I went over and knocked but no answer. It’s definitely not chocked. If I see them come home I’ll go back over. I’m worried as soon as the weight shifts loading it that it will just go down the hill.
Trailer emergency brake is probably pulled. Not ideal, but it’s probably not gonna go anywhere even if they start to load it like that.
It should really be chocked though
Chocks are cheaper than any incident that could occur without them.
