I've had the Burley Flatbed for 4-5 years and love it. It's a great trailer for my purposes.

I also have a Burley Solo that I got for my youngest. It works well as a covered utility trailer as long as the load isn't too big, in volume.

I have no experience with their cargo trailer, but do have a Wike Woody Wagon that I've had for a couple years. Maybe mine was put together on a Monday morning or a Friday afternoon. I've had zero problems with it, in fact it works well; but I think QC could have been a little tighter. Particularly on the welding.

The other trailers you list I have no experience with.
