You may already realize this or I may be incorrect but it sounds like you're describing the capacities stamped on the coupler at the front of the tongue. These would be expected to be quite a bit higher than the actual weight of your trailer or tongue. Those numbers apply strictly to the coupler and don't necessarily imply that the rest of the trailer is built to support those weights.
That is exactly what I was describing!
Let's get something out in the open about me:
I was thinking that these numbers were way high. The trailer's dry should only be 500 - 800 pounds higher than the Bigfoot
17. And the tongue weight should be between 450 - 500 pounds. The numbers on the stamp I was looking at mirrors a Bigfoot
21 or 25.
But what is the purpose of the stamp by the coupler. Why is it so high?
should I be looking at with respect to an appropriately sized electric tongue Jack?
