Question:

I have a 2020 Silverado with a 9300 LB towing capacity. I pull a 26’ RV 6885lb with a recurve r3 weight distribution hitch and +- 850 LB tongue weight on trailer not including +-100 LB of cargo in truck bed. The trailer sits level when attached, but I have sag on my pickup +-2” when attached. I also have ‘bounce’ on pickup when traveling and hit bumps in road. Should I add air bags or what do you suggest to help with the bounce and sag? Seems to me I could replace factory shocks with a good heavy duty shock but would I need to have my WDH reset? Any suggestions would be greatly appreciated! Thank you.

I'm guessing your 2020 Silverado is a 1500 model, correct?

A few years back, the truck manufacturers started giving in to customer pressure about the harsher ride quality offered in their 1/2 ton trucks. The result of this is trucks with a more car-like ride, at the cost of rear suspension firmness that helps control the sag and bounce you speak of.

A properly adjusted weight distribution system is important. If you're still getting sag, I'd make sure that the trailer's tongue weight isn't more than the system you're using can handle, and that the system is correctly set up. The system you're using should be rated for 800-1200 lbs like the Equal-i-zer # EQ37120ET.

Rather than an air helper spring system that can leak, I'd recommend the RoadActive Suspension, part # RAS4611. The RAS # RAS4611 will eliminate axle wrap and wheel hop as well as reducing sway and body roll. The extra support for up to 2000 lbs will help level the vehicle's ride height as well as reducing that bouncy, floating feeling you're experiencing. All without negatively affecting your ride quality when you aren't towing or hauling.

The RAS system can increase the ride height in the rear of the vehicle by up to about 1-1/2 inches, which could require you to revisit the adjustment of your weight distribution system.

I've linked to a product video that explains further how the RAS system works.
