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.
I doubt that trailer has brakes at all. It looks like a normal 4 wire brake light connector and the wheel wells are pretty skinny.
That connector looks exactly like the round 7-pin plug on my trailer. I don’t think I’ve ever seen the T-handle support on a flat-four plug? And as for brakes, you wouldn’t see any difference as the brakes would sit inside the wheel rim anyway. I currently have a four-wheel trailer and am taking a break to eat some lunch before I go back to welding on the new 5x9 trailer I’m building, so I’ve done a few calculations on the space needed for trailer brakes. 😄
