Seems to me #1 you do not understand basic pyhsics, and #2 never beefed up a set of leafs springs- thus adding weight - and got worse traction when done.
With your reasoning - take the worst-case scenario. Take a truck with springs so hard they do not flex at all when not loaded. Add to that a HD frame that does not flex. Then drive over rough uneven ground. Now - tell me - since you say it make "no difference" - how weight will be distributed evenly to all drive wheels when a few may not even be touching the ground. And a standard open differential that will send most of the drive-power to the wheel with the least traction - i.e. the once barely touching the ground. What happens?
I find some of the "makes no difference" comments here a little baffling. I'll have to assume that some of you guys never worked on leaf springs, drove on icy rough roads, and/or never tried out different setups on the same roads.
Back when 2WD Chevy pickups had rear coil springs, and GMC and Ford 2WD pickups had leaf springs - the better traction with the Chevys was amazing. But, they were useless for carrying heavy loads.
1967-72 Chevy trucks were available with standard rear trailing-arm coil springs and had much better traction - then if you special ordered the same truck with HD leaf-spring package. GMC was the opposite and came standard with leafs and coils were the option. Anybody who drove those trucks in the woods or bad roads knew the big difference in traction between the two setups.
And anybody that ever drove a leaf-spring truck with brokeh/worn out springs also should of noticed better traction.
And, I'll say one more time. Modern (and/or new) leaf springs are usually progessive rate and allow more un-loaded flex, then a non-progressive, or built-up set of leafs. Back 20-30 years ago, it was a common practice to beef up leaf-spring assemblies by adding many leafs - which made traction a lot worse.
Note also, you can stick a set of air-bags in coil springs - make them rock hard, and cause the same problem on eneven ground if your frame doesn't flex a lot.
Did you ever pull a dual axle trailer on rough ground and notice a wheel in the air not even touching? Or, does that "never happen" also. The same physics applie to a pickup truck, except on the truck the axles are further apart and are designed to move more -unless somebody screws them up.

Today's Featured Article - Tractor Profile: Farmall M - by Staff. H so that mountable implements were interchaneable. The Farmall M was most popular with large-acreage row-crop farmers. It was powered by either a high-compression gas engine or a distillate version with lower compression. Options included the Lift-All hydraulic system, a belt pulley, PTO, rubber tires, starter, lights and a swinging drawbar. It could be ordered in the high-crop, wide-front or tricycle configurations. The high-crop version was called a Model MV.
