What you're dealing with is not unusual ... somewhat expensive but fairly routine. I've dealt with many more extreme situations.
Take, for example, what I encountered when I started restoring the RM350 chassis. Someone, for some completely inexplicable reason, had put the rear springs on the front and the front springs on the rear. (Confirmed by matching the numbers stamped into the springs with the Dodge OEM Motor Home Parts Catalog.) Seven leafs on the front and three or four on the rear. (I think this is documented several hundred pages back in this thread.)
I can barely imagine what driving it that way was like and the thought scares the wits out of me. The cab probably felt like a bucking bronco and the rear probably gyrated more than the best hoochie-coochie dancer.
Honestly, if someone held a gun to my head and gave me a choice of driving the motorhome that way or mating with a moose, I'd choose the moose. Either way, I'd be going to hell but the moose would be the less intense and slower route.
As long as you're messing with the springs, replace the shackle bushings. I'd probably go with polyurethane bushings from Energy Suspension or Prothane. Also, check the shackle hardware and mounts for unusual wear and tear. (New U-bolts are a good consideration.)
