Do you hear the thumping a certain amount of time after filling the fuel tank? I have noticed that some time after filling up i also hear a thumping sound, it could just be fuel sloshing around in the tank. Have you had the struts replaced this is 03 everyone seems to forget these things need to be replaced too.
Could be any number of things, like your exhaust making contact with the body or frame. Best bet would be to actually get underneath and try to find something loose, or take it to a proper mechanic.

It is more than likely that you need a new strut
Pinion yoke. These trucks had a problem with them. Theres plenty of info on forums about it. Theres a replacement thats supposed to fix the factory issue costs about 300$.

It could be a suspension part such as a control arm. I just had replace the rear control arms on my 1993 Toyota Celica because the bearings in the control arms were worn out. It made a lot of rattling and thumping; when I replaced the arms the sound stopped.
You should have someone pull off the hubs and check your bearings to see if they need to be replaced or just repacked
Front rotors are warped and need to be replaced. Could be an out of round disc brake rotor
Wheel joint, u-joints, Center support bearing.
