If your engine has been taken care of and properly maintained(i.e., new plugs, plug wires, etc.), then it's the fuel. First try name brand gas like Mobil or Exxon. If that doesn't help, then try premium gas. The rattling you hear is called "knocking" and it's occurring in the combustion chamber. If the premium fuel doesn't cure it, then you might want to get the EGR system checked out.

Go for the cheap suggestions first: Higher octane gas, or take your truck for routine maintenance. An oil change with a chassis lube can work wonders. A transmission flush can run $200 or more, but is also a good idea if the rattle is related to an automatic tranny hitting a lower gear while going up hills.
Also, if changing gasolines fixes the problem, consider adding a bottle of fuel additive with your next fill up. One bottle is like $10 or less at any auto supplies store.

The octane rating in the the gas is too low,use a higher grade of gas 89 or 91 to stop the pinging.

Bad Gas?

could be your main bearings in your crankcase. Try starting out in second on a slight incline slowly and if that happens, your time is short.

Octane ping, loose catalitic cover, lifter noise, rod problems. What have you checked out so far?
