Living in northern New England, the only available equipment comes via the internet and UPS.
Finding someone who is offering a free diesel dually would be easier than finding anyone who could custom build shocks here.
I already have a BigWig sway bar.
Perhaps to explain better about the side to side movement- if I drive slowly across a wide dip at a diagonal (think of coming out of a gas station at an angle) one rear tire drops into the low gutter at the edge of the road. The truck and camper tilts to that side due to the stiff springs and the swaybar but the springs and swaybar want to quickly rebound in the opposite direction. THAT is the motion that I want stiffer shocks to control.
That is just one instance. Remember that the shocks are the primary thing that slows spring movement (a swaybar is just an uncoiled spring)
