Re: Camper Package on F-350

You must have had 19.5 tires on that F-250.

I asked AI about this and it agrees with you on the dually springs.  I asked which would give less sway dually springs or lower stableloads.  Here is the response.  

Short answer: Both help, but a full dually (DRW) spring pack will generally reduce sway more than StableLoads alone — however, StableLoads (especially when paired with a beefy rear sway bar) usually give almost the same anti-sway benefit with far better empty-ride comfort.

Since I already have the stableloads, if I decide to keep this truck I will just add a larger rear sway bar.  Most times I use the truck there is a heavy load on it but it would be nicer to ride empty with the stableloads.
