IMO you will need higher rated spring bars, and/or a higher rated WDH for the 21QB. I agree with your assumption that you will exceed a 600lb loaded tongue weight.
The 2019 21QB has a 6,500lb GVWR and a "published" (web site, brochure, etc.) UVW of 4,455lbs. If you refer to the 'yellow sticker' on the side of a 21QB many "as shipped" UVW's are approaching 5,000lbs (includes LP tanks filled).
Since we all have different loading requirements/habits, our ready-to-camp TT gross weights and tongue weights will very. Some folks frequently tow with full fresh water tanks, load for family of four, ...., etc..
Hypothetical conservative - moderate loaded 21QB: (5,000lb UVW) + (500lbs cargo, no fluids) + (50lbs dealer battery, etc.) = 5,550lbs gross weight
Loaded tongue weight @ 5,550lbs: 721lbs - 832lbs range (13% - 15% ...... recommended & common scaled range)
Worst case scenario @ GVWR 6,500lbs: 845lbs - 975lbs (13% - 15%)
Once you have your TV/TT combination under "typical" ready-to-camp loaded conditions (full fuel, passengers, cargo, etc.), a CAT scale visit would be a great way to confirm all your weights, WDH adjustment, etc., based on your typical towing conditions. You wouldn't have to re-visit a CAT scale unless loading habits changed dramatically.
