Ya, a empty light trailer that is unloaded will bounce a lot. Just physics. And really, nothing worse then backing up a short trailer. Best thing I did when I rebuilt my trailer the first time was to extend the tongue. Tows so much better now. Mine is only 8" long, but its also almost 6 foot wide, and gives lots of room. A bigger trailer weighing more, will always bounce less. Really to get a small trailer to handle any real weight, the springs have to be pretty stiff, and that just makes then rock hard empty. Also it is harder to balance a smaller, single axle trailer. Being so small, light, and short, the balance is so different empty vs. full. SO many of the newer small trailers also seem to have more design focus on ease of storing, then actually towing the thing!
