I agree with the rest, but to answer your question on the booster, here is how to test it. Remove the vacuum hose from the booster at the intake and cap it off snugly. Drive the truck-REALIZING THAT IT WILL BE HARD TO STOP without boost assist!-allowing extra space to stop. If the same symptons remain it is not the booster.
