Using a WDH to compensate for cargo added behind the TV's rear axle is an antiquated concept originating in the 1950s-1960s when the family sedan was a typical TV.
IMO, selection of WD bar capacity for use with modern TVs should not be based on amount of weight carried behind the rear axle.
---The amount of extra cargo weight I put into their formula is probably more than I would ever have so a 10k hitch would probably be fine but I am wondering what is the harm in just getting the 12k hitch "just to be safe".
The Equal-I-zer installation instructions make no mention of using the WDH to compensate for TV cargo. The instructions state:
"
While installing or adjusting the hitch, the tow vehicle and trailer should be loaded just as they will be while traveling. This includes full propane and fresh water tanks, and any other cargo (passengers & gear) the tow vehicle or trailer will carry, including ATVs for toy haulers.---
"
This means that, when the "unhitched" front-end height is measured, the effect of TV cargo already is included.
Adjustment of the WDH is intended to compensate only for the effect of tongue weight.
It is not necessary for the bars to have extra capacity to compensate for TV cargo effects.
To put it another way, if somebody asks me what size truck do they need to tow a popup then I would say any half ton should be fine but there is no harm in getting a 3/4 ton or 1 ton truck. Is this true for the Equalizer hitch also?
I think that depends on the construction of the TT.
Having a heavier TV with stiffer suspension and/or WD bars which are stiffer than necessary, can result in larger forces being transmitted to the TT's A-frame.
Another thing to consider --
The weight ratings of today's WD bars most likely are based on the outdated assumption that the bars will be used in an attempt to achieve equal added loading of the TV's front and rear axles.
Most major WDH and TV manufacturers now are specifying that none of the tongue weight should be carried on the TV's front axle.
This means the WD bars now are distributing relatively less load than in the old days.
