To help reduce rear sag when hooked up to your camper the best option in terms of rear suspension enhancement is an air bag system. This will let you actually fill the bags up when needed to close up the gap between your bump stop and contact point with a heavy load.

For your 2018 Chevy Silverado 1500 4x4 I specifically recommend the Firestone Ride-Rite # F2430. These air springs will provide you with up to 4,800 pounds of load-leveling support and their unique double-convoluted construction essentially creates 4 layers of reinforced rubber for excellent durability and an extremely long lifespan.

In addition to filling the bags up when you're hooked up to the camper (or when your bed is full of cargo), you can also let air out to maintain a smooth ride when you're traveling empty. This gives it the advantage over standard jounce-style springs like Timbrens that can often create a pretty rough ride when you aren't actually hauling a load. Jounce-style springs also won't do as good a job of reducing rear sag since the truck still needs to drop a bit before they will even engage.

I have attached a short video review that you can check out as well.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
