Shakes or Wobbles problem

Truck shakes when at a stand still / accelerating - once moving, stops shaking - will shake from time to time when speed changes - usually around the 30mph range - just started recently

You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!
If no leaks found check the idle air control.
