guys my 2001 le has a rattle that seems to be coming from the right rear. it rattles on bumps but if it is under a load like when towing it can be constant and will reduce when i get off the gas. Ihave checked everything I can under the vehicle and have found nothing. help

most probably your rear links... They can be hard to diagnose as once you put the truck up on a lift, they extend and you can almost not detect the slack in them,,, but once on the ground there will be a sweet spot where the joint has wear... They are pretty cheap and is a good start if you are certain that everything else is tight.

Check also the suspension and exhaust.
