If you are just driving then it could be your wheel alignment, also maybe the tire has been worn off improperly and is wobling, or could be a loose nut if you recently did a tire change or maybe it just came loose.
If it happends when you brake it is the wear of your brake pads on your rotors so maybe pads or rotors need to be replaced.

If your truck is rear wheel drive (which it almost certainly is), you probably have a badly worn U-joint (universal joint) in the drive shaft, which will eventually come apart leaving you stranded with a big towing bill. This will vibrate at any speed, and much worse as you acclerate, but might let up as you ease off the gas. In any case, no matter what the cause, you should have it repaired by a technician before you have a more serious problem.
