I wanted the 10K but none were available so I went with 14K. I called Doolittle trailer mfg and asked about torsion axles. I was told that sometimes over time, torsion axles change (gain memory) and get weaker. I don't know. But I got slipper axles with self lub bearings because of what I was told.
When you add your tractor, chains, binders, trailer weight, spare, and an implement, you may find it overweight on a 10K.
I have taken my trailer many times empty to pick up my tractor or other loads. Wonder what he thought the problem was traveling empty? Never heard of that. But I have heard of bending an axle when traveling overweight (like being too heavy and not slowing down for railroad tracks. )
I am glad I got 14K. I would have regretted the 10K and struggled to keep it within weight limits. My trailer is a 14K 20' tilt bed Doolittle EZ Loader. It tracks well both empty and loaded.
