He actually suggested adding a leaf - they have a kit specific to my application. Replace the bushings if needed, but he said they frequently don't because they're ok. The factory tapered 3-leaf spring is rated at 3450 lbs, so it's likely the coach has always been 'under springed'...
I'm strongly considering this route.
I would like to find some replacement rear frame rubber bump stops - mine have clearly taken some punishment. But, I'm having trouble finding these - my Ford dealers around are pretty much a waste when it comes to parts for this old coach.
