Jnoflane2, Welcome back. The pup & trail bikes sounds like my kind of weekend. And like you love my Ecodiesel. I have a small transporter business and use my ED. We deliver a variety of TTs & THs for 3 manufacturers and routinely boats & cargo trailers and or with motorcycles & snowmobiles in the bed as backhauls.
Naturally I use a no sway WDH. After that I bought air bags to help support & control the suspension in part for gravel driveway wash outs & such when heavily loaded. Because as you know the spring rate is set soft for ride. I decided to try this per a conversation with a designer/manufacturer of a small axle to frame air bag company. I had used in coil bags before in full frame coil suspension cars with reasonable results. So I decided to invest a little money & try it out. Frankly they have far exceeded my expectation. No more wallowing through that stuff. And the ride is not harsh or bouncy just firmer smoother & more controlled.
My advice after getting to know this truck ie not a HD & not a half ton leaf spring truck is to get axle to frame bags. Heavily loaded & some trial & error on the scales and they will compliment your WDH on the road. Before rough terrain I would relieve the bars. Just 12 or 15 psi will likely support the load & dampen the suspension. Have not used them with the Equalizer but with my hitch I get a little more weight transfer than the hitch alone. I know this is opposite of what some expect.
And I know you didn't ask but I've had great luck with my GDE tune as well. The software driven turbo brake provides a lot of safety & confidence when your trailer & load is pushing you down a grade. It saves brakes as well especially with the factory trailer brake controller. I replaced my original brakes at 293,000. Anyway you can read about it on their site if you choose.
