Recommended Rear Suspension Enhancement for 2020 GMC Sierra 3500HD W/ Truck Bed Camper

Question:

Hello, I just purchased a 2020 GMC Sierra GMC 3500HD Truck because were buying a Truck Camper a 2021 Lance 850 model that should be ready on the 1st of June. Never before having owned any type of RV or even a pickup truck for that matter, I want the best and safest ride possible. Ive talked to the RV dealership and done some research but am still not sure what the best way to go is as far as air bags, anti-sway bars, the Tribren devices or, as I learned about last night, the Roadmaster Active Suspension system. When hauling the Truck Camper, gear and everything, the load will be right up to my trucks max load weight of just over 3,800 pounds. Any expert advice or suggestions will be greatly appreciated. Hope everyone there is having a good day.

Since you are expecting to have a payload of 3800lbs the best and safest suspension enhancement for your 2020 GMC Sierra 3500HD is an air helper spring kit like the Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle # AL57341 which offers up to 5000lbs of load leveling support when the camper is installed, but when you are driving around unloaded you can air down the air bags to the 5 PSI minimum and still have the factory ride quality.

To keep from having to manually inflate the helper springs each time you are ready to hit the road with your camper I recommend installing an on-board air compressor kit like the Air Lift Load Controller Compressor System for Air Helper Springs- Heavy Duty - Dual Path # AL25856 which will allow you to air up each spring independently incase the load in your truck is heavier on one side compared to the other, and you can adjust the air pressure from the comfort of your driver seat.

I included videos for both of the products mentioned for you to take a look at.
