Welcome to JOF
Just food for thought.., your TV's published Tow Rating of 6,800lbs isn't reflective of the "actual" tow rating. The following JOF thread will shed a little light on the subject: http://www.jaycoowners.com/showthrea...uot-Tow-Rating
The following may be a little more information than you need, but may provide a little insight on sizing a WDH......,
For now we will assume
an actual TV Tow Rating" of 6,500lbs. The 2013 26BH has a GVWR of 7,500lbs (UVW 4,570lbs) and exceeds your TV's actual Tow Rating of 6,500lbs (even the published 6,800lbs). So it all comes down to your TT loading habits, to be mindful that you can't load the TT above your TV's actual Tow Rating.
Ideally the loaded tongue weight for a 29 feet long TT would be 13% to 15% of the loaded TT weight.
For example, IMO this would be a conservative family loaded condition for a 26BH of: (UVW 4,570lbs) + (350lbs Ship Weight delta) + (125 lbs battery/WDH/dealer misc.) + (600lbs TT cargo, no fluids) = 5,645lbs....., thus a loaded tongue weight range of 734lbs to 847lbs..... so a WDH rated at 1,000lbs would be ideal and also provide a little cushion.
If you loaded the 26BH up to our assumed
actual TV Tow Rating of 6,500lbs the loaded tongue weight range would be 845lbs to 975lbs.... so the WDH rated at 1,000lbs would do the job as well.
Also, please note that the loaded TT tongue weight is subtracted from your TV's payload capacity.
Once you have your TV/TT loaded and ready for camping, a brief visit to your local CAT Scale will provide you with a wealth of information, thus confirming that your TT weights don't exceed your TV's weight limits.
