You can lead a horse to water, but you cannot make it drink.
That sticker on your receiver hitch tells you what it is rated for.
That has nothing to do with the axle load weights. You state that yours is 1130#.... But you really do not know what your TW is, as you only measure it with WD engaged. You cannot determine TW that way.
This means that it is very likely you are OVER the hitch rating.
You will only know, IF you weigh it properly.
Now it is your decision. You have now been lead to the water.
Drink the water and know the truth.... Or don't and not know.
Your money, your choice
