Mine is all steel, beavertail, ramps slide into deck.
Started out as an economy trailer, been great for almost 30 years now.
I like them as low as possible, so I run 14" tires.
Sometimes it carries some 4- and 8-foot 2x8s for really low cars or difficult angles.
I added a pickup-truck toolbox on the tongue and a fenced tray between that and the deck.
That way it carries everything needed, houses the electric winch, battery, floor jack & etc.
I also had bedliner sprayed on the deck and tops of the fenders.
I can plug the winch into a feed from my truck, or use its own battery, depending on what I'm doing.
Electric brakes on all 4 wheels.
