Sumo Springs or Air Bags

I have a 2018 DCSB TRD Off Road. KB Voodoo mid height rack and CVT MT Bachelor tent mounted. I am on stock suspension with no desire to lift at this time. The stock form takes me almost everywhere I want or need to go at this stage.
With the added weight of the rack, RTT, and gear I take with me I would like to support the factory rear suspension a little more and reduce the ass end sagging. Advice on either Sumo Springs, Air bags, or anything else. Thanks in advance.

 

sumo springs are great and you have two different load ratings to choose from. but they can affect suspension travel a bit once they begin to compress. sounds like it's no issue for you. they could be good and simple. i am on the lighter ones, but i don't run that weight in the rear so can't compare.

 

I camp about every other weekend so therefore my tent and rack stay on the truck all the time for convenience. Combined that is about 160Lbs on the back all the time. Then with camping gear, dry goods, and cooler I probably add another 300lbs on top of that. I run FSR and gravel roads and don't do any technical off-roading(I have my 04 TJ for that).
St. Germain-you stated you have the lighter spring rates. How do you like them? Happy with what they do?

 

I have a Snugtop canopy and drawer system in the back of a TRD OR long bed with approx 350 lbs constant load. Running a AAL and 610-40 Sumo Springs in the rear to support the weight. The ride is good and the Sumo Springs really help to prevent body roll. Got about 1/2” lift to counteract the sagging from the weight of the cap and drawers.
