Hmm i'm wrong... the legal load capacity is 1930kg, which means 570kg empty weight...
You can buy a 430kg 2 ton trailer, but those are disposable junk, made of 2mm pressed steel... Mine has a truss frame.
In Europe the 2 ton tandem deck-over, is the most popular light commercial trailer. extending trailer length, quickly adds weight because a longer bed needs stronger frame members too... Though i sometimes wish i had more length to balance out the load better, a shorter trailer takes less storage room, and i'm not dragging dead weight along when just getting a few 2 by 4's...
What i want to do this winter, is put it on smaller 13" tires and drop the deck 6 inches, so i can use shorter ramps, and it has less wind resistance with a tractor on it. It makes a noticable difference in fuel consumption.
