Unusual tire wear

[SkyBound]

We just completed our last trip of the season. After 37 nights and about 3000km we had no significant issues. I have noticed, however, the driver's side rear tire of the trailer is wearing on the inside of the tread only. All other 3 tires look good. What could be causing this wear? How difficult is it to perform an alignment on trailers? It doesn't really look like there is much in the way of adjustment under there.

Axles are Dexter 3500lb, total mileage on trailer is less than 5000km and tires (stock TowMax) are always at 50psi.
