I haven't had any real chance to use the trailer for recreational purposes yet, but today I put it to work bringing some topsoil home. I loaded it with 21 40-pound bags of topsoil (840 lbs.) and a 10-lb. bag of grass seed for a total cargo weight of 850 lbs.
The trailer tracked really nicely with that weight in it, and was extremely smooth.
I was running the 3-Axis Coupler so I could give that a good test with a full load. It's easily the quietest coupler I've ever had - no noise from it whatsoever.
