Random questions mostly suspension

So i took the new rig on a 600 mile trip last night COMPLETELY EMPTY 40 PSI in both duals and 70 in the front and holy crap it rides terrible on some freeways. Talk about a bull ride it reminded me of being on my old long 24v long bed cummins. Which leads me to some questions

Is this just the factory Rancho's everyone complains about ??

Back in the day we used to just take the rear sway bars off our dodges and that helped alot with off camber freeways and just smoothness all together has anyone done this??

Should just just put a full Carli Kit on this truck leafs and all with bags and run 19.5??

What is the largest tire you can put on a stock dual ?? and i dont mean squeezing a 12.5 on there i mean workable with no spacers like 265 285 ??

How many leafs are in the dually leaf pack? I thought you didn't like the full Carli leaf springs you had in your 2013? Why not just changed out the shocks and lower your tire pressure when not towing and see how much that helps? As for you tires, go measure the distance between your duals and see how much room you have. That should help you decide on what size tire to run. I didn't like the ranchos because they didn't last long, that's my complaint. A dually has the heavy duty rear springs so good luck getting it to ride nice in the back

Bfg makes a 255/80R17 mud terrain that is supposed to work. I would think 19.5s would make the ride worse. Cheapest fix would be some weight in the bed. I doubt shocks will make any difference. It's those stiff springs giving you a stiff ride. Do you need 70psi up front or can that be lowered?

Also I think there are dually wheels with additional offset between the duals. Ultra gauntlet maybe?

I've got a 14 350 drw, I had the same complaints as you about it stock, so I put the carli 2.5" pintop kit on it with the mini packs in the rear and the longest leaf of the mini pack removed cause it doesn't fit. It rides EXACTLY the same after the carli kit install, no difference in ride at all. If I was to do it again I would just keep the rancho's and add a spacer block for the leveling kit and save a crap load of money. The only thing that's going to improve the ride is swapping out the entire leaf pack, but then even with a full carli leaf pack and airbags I believe you are only upto the load carrying capacity of a stock srw 350 spring (which is less than a stock drw), which defeats the whole purpose of having a dually in the first place aside from the extra stability while towing. I put 2000 miles on my truck with everything stock and just the carli kit and the ride was still just as bad as stock. I'm now running 37" toyo's and 22" 10 lugs and it's even worse, but I haven't had time to adjust air pressures yet and they are all at 60psi which is way too much.

This is sort of funny because my truck is a 2004 f350 dwr and I have been wondering how the new trucks ride.My truck is better but is rough .I have converted the front to 05 and up coil springs and have just put 2011 f350 srw leafs in the back,while it is better,it's still not as good as I would like it to be.I want to see what you do to improve your ride.Nice truck I would like to have a new one in time.
