Will Stable Loads help with o/loads already engaged

I own a 1998 Lance 990 Legend and manufacturer sticker shows 3259 lbs. dry.. 4000lbs. wet CAT scale 11,300 lbs. with DW, grand daughter and a lot of stuff. By my self 3600lbs. Very comfortable with mods after 6000 miles hauling camper on my 2006 Dodge 2500 4x4 CTD long bed truck. Very little squat with suspension upgrades. Only use 15 psi in airbags. You have the right truck for sure with this model.
