For your 2018 Ram 3500 that will be towing all the time very near the towing capacity the higher rated Timbrens part # TDR3500CA would be what I recommend as they can provide up to 8,600 lbs of support. This will give you the support you need and since it's not an air bag kit it will basically require zero maintenance and have a very easy install.

Hey Steve, thanks for the pictures! I was able to use the S/N to identify the pin box, which is in fact the Rhino Box. I would choose the B&W Gooseneck Pin Box #BW23RV over the Shocker Hitch #SHK99YR for your 2026 Alliance Avenue 25RL. B&W…
