NEWER ARCTIC FOX 1150 ON DRW

I have a 2012 AF1150. It was originally on my 2008 Ram 35000 dually. I added Stabil Loads to engage the overload springs earlier AND added air bags, running them at about 60 PSI. The rig COULD handle it, but it was right at it's limit and frankly was twitchy on curves and bumps. It occasionally porpoised on uneven highway. I upgraded to a 4500 and there's no comparison. No mods needed, instant recovery when turning, with little or no tilting, and it drives like a lexus. It's your call. Many folks on this site are doing fine with the 3500, but I still think your at or beyond the limits of the truck.

WOW, 60 PSI Seems high, I run 12-15 psi fully loaded 13K ON TRUCK AND 7500 LBS TRAILER. Just to level. I would love a 4500 RAM but not in the near future. Hope the 1150 is not much heaver then my old 990 M

Thank you, Andy

It was actually about 60 psi on the passenger side and about 30 on the driver. I believe the side with the slide is just heavier.
