Unfortunately most RV dealerships don't know how to size and/or adjust a conventional WDH correctly, especially a Reese HP Dual Cam WDH like you and I have. When a RV dealer tech does make the proper WDH adjustments, the adjustments are only good if one plans on towing an empty TV and TT......, the dealership fails to inform customers that once their TV and TT combination is "loaded" for camping the WDH will have to be check again for adjustment, ideally at a CAT scale.
Your 2011 G2 29BHS has a published UVW of 5,475lbs, GVWR of 7,700lbs, dry hitch weight of 715lbs, and is 30'-6" long. An actual moderately loaded 29BHS would weigh around 6,700lbs (easily heavier depending on your personal loading habits). At 6,700lbs one would want a loaded tongue weight of 871lbs to 1,005lbs (13% to 15% of 6,700lbs)......, so your 800lb WDH isn't adequate.
IMO a set of 1,200lb spring bars would be a good investment.
WDH spring bars alone don't actually prevent/control sway, but a proper rated WDH spring bar will enhance the TV's handling of the TT under loaded conditions. Since you have the Reese HP Dual Cam WDH (integrated sway control), your HP Dual Cam sway control feature will be much more effective with the 1,200lb rated spring bars with a loaded tongue weight well above 800lbs.
If you would like further detail on adjusting a Reese HP Dual Cam WDH, feel free to start a new thread over in the "Towing and Tow Vehicles" forum with any specific questions.
A brief visit to a CAT scale with your loaded TV/TT combination will tell you a wealth of information (TT weight, tongue weight, confirm WDH sized/adjusted correctly, axle weights, TV within weight limits, etc.). The following JOF link is CAT scale "how to" weigh a TV/TT combination and breakdown the data: http://www.jaycoowners.com/showthrea...igh-Your-tt-tv
Under normal towing conditions one shouldn't "have sway that is manageable"..., a sway condition should be an extremely remote event that most never experience.
