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.
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. 😄
