Question:

2015 GMC Sierra SLT 1500 Z71...no mods to suspension. TT is 5000#s - have WDH and sway bars, wondering if I need Sumos or airbags to ensure a much more stable ride even without the TT hitched up. if something will improve the ride please forward your recommendation

I actually recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS4611 which is confirmed to fit your 2015 GMC Sierra SLT 1500 Z71 and will not only improve the ride quality and sway reduction when towing your 5000lb travel trailer, but will also improve the unloaded ride quality by reducing sway and body roll.

The # RAS4611 has a 2000lb load leveling capacity which is perfect for your application, and does not require any drilling.

I included a video of the # RAS4611 being installed on a similar 2013 Chevrolet Silverado for you to take a look at.
