Hard to tell with the pics, but I either don't see lights or - if that crushed thing on the aft-left corner is a light - it's doing to need that as well.
It looks like there's a spare tire, but no carrier. The winch also looks small. Then there's the "feature" of twin axles - with a trailer with this many issues, that's going to be twice as expensive to make and keep operational.
Another feature to look for is something to step on to get yourself up into the boat - I don't think this trailer would support a person.
