When old, we need low rider trucks with carrying capacity.  I have 7 leaves in my rear spring pack, each side not including the overload leaf, which is there for looks.  It's never contacted the hangers. I'd remove it but thats too much work.  5 in the front spring packs.
No wonder my wife hates to ride in it when I don't have the truck camper in the bed.  The camper smooths out the ride....  somewhat.  The one saving grace is I have the longest wheelbase Ford had in 1997.  The truck is 19.5 feet long, front bumper to rear step bumper.  Makes for interesting parking lot turns.
