First off, you loaded pin weight will be closer to 2900# than the dry 2300# from the brochure data.
The tow ratings on the website are manure in my opinion. The numbers they list are based on a stripped model truck and a 150# driver. You need to work the specific numbers up for your truck.
First look for the yellow sticker on the drivers door jamb. There will be a paylaod rating for your truck. This is the most load you can add to the truck bed and passengers.
Use 20 to 22% of the trailer GVWR for an estimated loaded pin weight. Now add the estimate pin weight plus a hitch plus cargo in the bed plus passengers. This total has to be less than the payload capacity sticker.
Adding air bags is a crutch and does not increase towing or load ratings or safety.
A 3/4 ton truck will reach its payload capacity before you reach the maximum towing capacity.
