If you're towing most of the time then I would go with the Timbren Rear Suspension Enhancement System # TGMRCK25D. These will provide the most support for your 2020 GMC Sierra 2500 while towing your 5th wheel. If you're more concerned about ride quality then the RoadActive Suspension # RAS3611-HD would be the better choice. The Timbren has a tendency to be a bit rough when you aren't towing or hauling.

If you want the best option possible I would go with the Firestone Air Bags # F2709. These will provide you with 7,500 lbs of load leveling capacity. Since they're adjustable you can set them right where you need them to add extra support while towing. You can also take them down to the minimum psi when you aren't towing so they won't impact your ride quality.

Any concern about the bags going bad? Is there maintenance involved? Thank you very much

@Perry sorry for the delay our comments weren't coming through. The air bags have a lifetime warranty so no, there is no real concern that they will go bad. The Firestone air bags are incredibly well constructed. The only maintenance is making sure they maintain the minimum 5 psi if you deflate them when you aren't towing.

So does it come with a compressor and remote or something like that? I like convenience, thank you Perry

@Perry an air compressor is something you will have to add separately. You will need one with a max air pressure of 150 psi to fill the bags. For an option that has a remote, works with your smartphone, and has enough pressure I recommend the Firestone Air Command Heavy Duty Air Compressor # F56VV. This is a single path system so it will keep both at the same pressure. If you want to be able to adjust the pressure of each air bag individually the # F99VV would be the best option.

I checked out your 2016 Solitude 321RL and since it has a tapered nose and an extended pin box you wouldn't need a slider hitch installed in the bed of your 2020 GMC Sierra 3500. You could use the B and W Companion Fixed Hitch for GM rail kit…
