Yes, you are correct. There are variable or dual rate coils. Just as leaf packs can be made to be more linear. At any rate (get it?) my point was leaf springs tend to handle higher loads better than coils.
A while back my neighbor came by to check out progress on my truck. He was stating that he had converted his old 71 c20 with a big camper from coil to leaf and how much better it was after the change.
