2013 Chevy Express Modified Rear End and...?

We are purchasing a Jayco 23MRB. I have a Chevy 2013 Chevy Express that won't meet load specs. We are replacing the rear end with a "2500" rear end which will give us ample capacity. The mechanic asked us if we wanted to put air bags on the springs and add a sway bar to the van. Any suggestions on this would be appreciated.

Will the existing springs meet the load requirements?

If not, air bags or uprated springs will be required.

And double-check, there may be an anti-sway bar already installed.

I would go air bags over new springs.. When not towing you can drop the pressure in the air bags for a better ride.. cannot do that with springs..
Sway bar YES.... bigger is better... 3 months after putting the biggest sway bar on my truck that I could get a semi on I-15 forced me off the road.. while towing .. I firmly believe that monster Helwig sway bar helped save my life or at least my truck and trailer.. I also credit the Hensley Arrow hitch...

Smile 2500 Rear End on a 1500 Chevy Van

Hi Seann: Thank you for the reply. The truck repair company who is installing the new rear end said the springs are fine. There is no sway bar built in. We want and saw the 23MRB again and are moving forward. The van goes in tomorrow to start the process. What a process, had to find wheels; only 1 set in 6 hours had the proper offsets to the 2 sizes. Then tire company informed me that due to the higher pressure on the tires we are purchasing, the on board computer might call out an improperly inflated tire pressure. He wondered if the dealer can adjust that setting on the onboard computer.
