Talk through that with Ben. I tow regularly but its only a small Turtleback Trailer with probably 150lbs tongue weight. I didn't consider it in my suspension work. If you have a lot of tongue weight, I would seriously consider a solid weight distributing hitch setup well before airbags. Having used both with regularity, a properly set up WDH is safer and much more manageable long term than airbags.
You guys aren’t getting the ‘standard’ tune? What gives? I contacted King directly and they recommended their ‘standard’ tune. I sent them front and rear axle weight - truck is 6800 lbs when fully loaded.
edit: didn’t realize I was posting in the 200 forum. I’ll see myself out
