Question about WDH hitches for your TCers

My camper is a Northern Lite and dry it is 3000# and loaded it is 3700#. I have a 2013 Ram dually and when I'm loaded I am under my GVWR by 1800# which is 14000#. I have a little over 7000# on the rear axle that is rated for 9750# with 65PSI in the tires. If I aired up the tires to 80PSI (which they are rated for 80 load range E) the rear ale would be capable of over 11,000#. The rear axle is rated by AAM of over 11,000#.

Thanks for the recommendation of 600# bars. This is in the range that I was thinking of also.
