The Cortes fiberglass trailer is relatively new and there likely isn't much actual experience with it yet. The Cortes trailer looks interesting for sure, but I wonder about its long term durability given that it uses a composite frame and axle spindles that bolt to this composite frame in lieu of say a Dexter torsion axle. It also has a composite rear bumper instead of the more conventional steel rear bumper that enables carrying bicycles, etc. And finally, it costs at least two times as much as a Casita trailer. So I imagine it is meant to compete with the higher end of the fiberglass market Big Foot, Escape, and Oliver trailers.
Personally, I think the Casita trailer provides the best bang for the buck and it is also very amenable to being customized and modified by capable people to create the ultimate trailer to satisfy the owners specific camping/travel desires and needs, e.g.:
