WoodTurner, these pictures contain the numbers that you need to guide your decision for a given trailer.

This is a company passionate about weights and ratings. They often set up portable scales at RV rallies and provide weighting services.
They have an advantage over CAT SCALE’s as they have portable equipment that is capable of determining the weight of each wheel(which is important). Most folks don’t have easy access to wheel end weighting, so the next best thing is to use the commercial CAT scales at truck stops and use the axles weight numbers to determine where they stand.
A reminder, everything you place in or on that truck reduces payload capacity.(yourself, your spouse, your pets, the hitch, tools, cross box, bed cover etc etc etc.) The goal would be to be within your numbers BUT have some margin for tummy comfort.
I will second Bill’s comments regarding the air bag comment. while it might help level things, it does not increase the ratings that have been established by the manufactor for a given vehicle. Also, just in case I wasn’t clear above, it will reduce your available payload as well
In no way am I making any judgements on anyone that uses air bags(they have their purpose), folks make their own decisions, based on their individual needs and I can and do respect that.
