I changed the spark plugs and the truck will idle fine in park and neutral but engine shakes the whole truck in drive and reverse just sitting there on the brake, What would cause this, would crossed plug wires only do this while in gear or even just in park so i dont think its crossed wires, cheapo plugs possibly?

If the wires were wrong, it would miss all the time. Recheck your work to make sure no vacuum lines are disconnected and recheck the wires to make sure they were not dmaged when the work was done.

Let me know what you find.
