I would first check for any stickers with a WDH weight rating limit on your TT's A-frame.
On the lighter A-framed TT's/HTT's (less then 3,500lb GVWR) I would tend to stay with the "lite-duty" WDH's if at all possible.
The 154BH worst case loaded tongue weight range would be 10% to 15% of 3,200lbs (GVWR) = 320lbs to 480lbs. With the limited CCC of the 154BH towing near/at GVWR will be easy to do. That being said, I would look for a WDH rated at 500lbs (ideal), but a WDH rated at 600lbs would be my maximum (would require extra care for proper adjustment).
You could go with a WDH rated at 400lbs (or 350lbs as referenced in my prior post 'link'), but it would require maintaining a loaded tongue weight within the respective WDH weight limits, which is very doable.
Ideally a WDH rated that gives you a little tongue weight wiggle room would be great because our loading habits do fluctuate...., normally heavier then lighter.
If choose to go with a WDH, a brief visit to a CAT scale will confirm your weights and WDH adjustments.

Hope this helps.
