JoeBlow is an unknown quantity at this point

I have the 32 gal. tank also, and I feel the thump from time to time. I do believe it's your fuel moving around, since it only appears to be an issue with trucks that have the 32 gallon tank and only happens when your tank has the right amount of gas in it. Next time it happens check your fuel gauge. I only notice the thump when my tank is between 1/2 to 3/4 full.

This question comes up every so often and cracks me up because I remember wondering about the same thing when I first got my truck and noticed the thump. Never heard the one about the "hill start assist" though.
