Sorry folks, I have to completely disagree, I think that’s not bad considering.
1, the auto reverse coupling is clearly banjaxed, shortening the drawbar.
2, more critical, look closely, that kerb is very uneven, why the trailer veers to the offside. It’s >3x the height on the offside. Quite a problem for a light trailer. Two choices, take a slight run at it, . . dodgy, or, do what they did. Line the trailer up dead straight to both the kerb and the van, then slowly Sqeeeeze over the rise.
In the distant past I’ve taken a grinder to a kerb I had to repeatedly reverse over, just to eliminate the above problem.
