I like the pockets/rails on the front of that trailer. Although it isn't clear if there is a back to the pockets to actually hold a stake. It is beyond me why they didn't go further forward as well as behind the fender with the pockets/rails.
I like using the pockets on my Morgan flatbed (no longer in business) for ratchet straps. At least for the strap end. There is no way for it to fall out when fed through a pocket, and I know the pockets are solid (channel iron).
As far as the I-Beams, I was seeing that in the Youtube reviews. It is a nice concept. It sounded like the trailers were slightly higher due to the I-Beams than many competitor trailers, but a stronger construction.
However, my Morgan is similar to what the presenter calls the double-6, and I believe it is a bit weak on the rear end. No cracks that I know of, but it seems to bend down slightly behind the rear axle with a heavy load on the rear. Eventually I'll do some modifications to strengthen the mid section.
3,351lbs is a HEAVY trailer. But it does look well built.
