Yes to both questions.
"Any" improperly installed and/or adjusted WDH has the potential to create towing issues, that can in some instances result in damage to "something"..., even with a properly weight rated WDH.
It's apparent that your salesperson doesn't have enough basic WDH knowledge to make a proper Equal-i-zer brand product recommendation, and/or "weight rating" selection.
The 28BHBE is a heavy and long TT, even under modest loading conditions, so I agree with the other comments that an Equal-i-zer E4 rated at 12,000lb/1,200lb is required (at a minimum). As mentioned, a 14,000lb/1,400lb rated E4 wouldn't be overkill, what's important is that the WDH is adjusted correctly to the TT's loaded tongue weight and the TV's front suspensions requirements (refer to TV owners manual).
Also confirm the "WD Mode" weight limits of your TV's OEM receiver.
At the end of the day, one should take their TV/TT under "loaded" conditions to a CAT scale to confirm all your TV/TT weights, tongue weight, and confirm that your E4 Equal-i-zer is adjusted properly to your TV's front suspension requirements (refer to TV owners manual).
