The stiff shocks are probably causing at least part of your ride problems. Stiff makes the entire truck follow the bumps, rather than just the wheels. Short sidewalls make this worse because the tire can't absorb anything either. If the length of the shocks is limiting the suspension travel, either long or short, it can cause ride issues too. As a test, try removing the front shocks and drive over a "known" bump. This will confirm or eliminate them. If the springs are too stiff, you may not see much difference. If they are soft, the truck will continue to bounce after the bump, before it settles. It may also bang the bumpstops. As a last resort, try swapping the front tires as a test. You may be surprised at the effect of the short sidewalls.

Nice looking truck BTW
