Well......mfg. have published MAX TOW Ratings that can be achieved when the 'fine print' is taken into account.
Yet the 'fine print' is rarely read or understood
*Maximum trailer weights in pounds for properly equipped vehicles with no cargo
*Maximum Loaded Trailer Weight assumes a towing vehicle with any mandatory options, no cargo,
tongue load of 10-15 (conventional trailer) or king pin weight of 15-25% (fifth-wheel trailer),
and driver only (150 pounds).
*May vary depending on model, trim and/or powertrain.
*Weight of additional options, passengers, cargo and hitch must be deducted from this weight.
You have a very capable towing machine.
Look for a 5vr with a GVWR of 15K with a floorlan you like and buy it.
You will be fine.
Shouldn't need air bags........worry about that AFTER you get 5vr and have it set up.
Level towing and good bedrail to 5vr overhang clearance.
Disc brakes...great upgrade and can't compare drums to them..but drums work very well.
After market exhaust brake...not needed. Your OEM works great
