Oh and I did want to mention that I do understand that my TV GVWR will be my limiting factor. I know the TV weighs 6400 with family loaded, full gas and cargo loaded in back (which some could be transferred to TT to offset weight from TV). So I have 800# payload left for hitch setup and tongue wt. My back up TT has a listed TW of 545, so I am estimating after TT is loaded a max of 685# TW leaving only 115# for hitch setup wt. That would be maxed which I am not wild about, so I would probably offset some cargo to TT to lower that.
