I have some confusion on this subject. I have a 12' long single axle trailer rated at 2000#. The deal is, the coupler and ball are rated @ 200lb max tongue weight. I was told that the tongue weight is 10% of your max trailer capacity. Now the deal is I decided to check this out, so I put a scale under the trailer jack and put 1 walk - behind on the trailer. The reading went off the scale - way over 250# at the tongue with just one 450# walk behind! This was however with the machine pulled all the way forward, which is where you would normally put it. My question is, do you have to try to carry everything over the axle to keep the tongue weight down, or are those "max" ratings unrealistic?
